So, this latest Guardian article on the subject seems internally contradictory, at least at face value.
It reads:

So from this I draw the following conclusion. Given that one 701 unit is currently stationed at Bournemouth depot and there is talk of
a train (singular) with GBR branding, set to run from Waterloo to Shepperton, I think we can be fairly certain that it will be that unit and that unit only which will receive the GBR branding for now.
However, I cannot quite work out whether GBR branding is understood to mean a simple vinyl job (as would be likely and most economical) or a proper repaint.
The fact that there is talk of a single unit getting special branding, with the next one being years off, makes me think it is a proper repaint / overhaul. However, the author also says all trains,
including the one with "special branding" will continue to run as South Western Railway for some time, whatever that means. So, that sounds more like a vinyl job i.e. a small Great British Railways banner or logo applied in addition to the current South Western Railway branding. Bit like the metropolitan transport authority logos on the new bus liveries for Manchester, Liverpool and West Yorkshire.
But if that is the case, why only bother with one unit for marketing purposes. Why not several? Is that for logistical reasons, because no other unit can currently be taken out of service? Surely more units could follow sooner than in several years time, provided it were a quick vinyl job. Or is it, given that the bill for GBR has not even been introduced in parliament yet, the branding is only provisional and set to change once GBR gets set up?
Perhaps it is a proper repaint, a kind of prototype livery, which prominently features GBR branding but also South Western Railway in small print. Kind of flipping the roles. That way the branding would not change for any of the other units, nor would the operator name. That is the only way I can make any sense of this article and of the e-mail stating branding would not change.
