The app for Apple/ iOS needs updating, I guess.
Whereabouts, exactly?

At Tottenham Hale Station.
Which needs a major rebuild to get 4th platform in so far cheaper and easier to put the masts on the 4th track bed for the time being which allows the 4th platform work to be done with the 3rd track still open...

Meridian water station code is MWRWSTN... bit of a mouthful isn't it!
The 3rd track looks to have been OLE-d entirely independently of the existing two tracks. As a result in the grand scheme of things, shifting an OLE mast is not that big a deal if you're going to come back and do something later that's bigger (that mighr require OLE changes *anyway*)
It's the stuff that's hard/disruptive to come back and change / excessively costly to do again that's more important, stuff like drainage or bridge alterations. Hence why the bridges at Northumberland Park and MW have clear space to put a 4th track.
Precisely...
Having looked at it more closely now:
From the start of the third line at Lea Bridge to Coppermill Junction, there’s no need for 4 lines, and clearly NR don’t think so either as the first new bridge is built single span only. So they’ve put the masts where needed for the third line.
From that bridge to Tottenham Hale, I guess it’s probable that there will be some form of big junction or flyover to get the lines from Liverpool St over to the east side of any future four track formation; otherwise there will be lots of expensive work at every station on the future four track section to get the platform configuration right. Also the Crossrail 2 portal will be in the area just north of the Barking line bridge on the west side (as per the maps issued in 2015). Therefore my guess is that all this area will have to be completely remodelled, so it doesn’t matter where the 3rd line masts go as they will probably be removed at remodelling, so put them where it’s easiest now.
Tottenham Hale. According to the Crossrail 2 consultation in 2015, some Crossrail 2 trains would terminate at Tottenham Hale. That means 5 platforms, or at the very least some turnback sidings immediately north. Possibly both. Also I’d be surprised if the current platforms are wide enough for the number of passengers who would interchange there to/from Crossrail 2 (its bad enough now). Put that together and you’re looking at a big rebuild there too, so, again, put the masts where it’s easiest now.
North of Tottenham Hale, all the masts appear to be right on the boundary fence (as it would be difficult to go outside) or well clear of a prospective 4th track.
So it looks to me like the project guys have done their homework, put masts in places clear of a 4th track where needed and possible, but where major works are required for 4+ tracking the masts have gone where it’s easiest now, as wherever they go they’ll have to be pulled up in future. Seems to me to be a sensible use of taxpayers money.

it'll be interesting to see what the track configuration will end up being for CR2, from the following option, where C: Crossrail 2, W: West Anglia Mainline, U: Up, D: Down
Paired by use:
DW|UW|DC|UC or DC|UC|DW|UW
Fast in the centre:
DC|DW|UW|UC
Slow in the centre- allows for having reversing sidings easily accessed
DW|DC|UC|UW
if either of the latter, cross platform same direction changes can be accommodated but ONLY if Tottenham Hale is entirely flattened and rebuilt as a two-island station. Alternatively if kept as outside+island it is possible (though unlikely, based on precedents from other stations) to separately gate Crossrail and West Anglia/Stansted Express and charge different fares...

The overall thinking is DC|UC|DW|UW up the corridor with CR2 taking over the platforms at existing stations and WA services moving over to 2 new tracks to the east with no platforms at most stations and all the grade separation done south of Tottenham Hale (remember all the Vic line stuff underneath to the north...
It's 4toh off-peak and morning peak, but 3tph in the evening peak (I think the main line changes pattern in the evening peak which busts the normal way of working the shuttle)

It was no trains at all when I had a wasted hour+ at Stratford yesterday afternoon. Six GA drivers stranded, unable to get to Orient Way. Not encouraging.

I'm liking the shorter journey times Northbound now that 2 trains per hour don't have to sit and wait at Coppermill junction. Now Lea Bridge to Tottenham Hale takes 3.5 minutes instead of the usual 7 to 10 minutes waiting for up and down Stansted Express and Cambridge services to cross the flat junction there.

Surprised the drivers didn't get a taxi or a Control special Orient Way to Stratford and back.
