Yeah, I was surprised at this as well. Vauxhall was closed on non-strike (or more accurately, action-short-of-strike) Sunday the 18th Dec. On strike days, Vauxhall is served by the Windsor Lines, but this Sunday, there were no Windsor Line services. So one could argue that non-strike Sunday was worse than a strike day.
Anyway, something interesting to ponder:
Today, I was at Clapham Junction and there was an engineering works poster on display, which was obviously prepared way before SWR realised what was going to happen on Sunday the 18th. The poster said that the New Guildford Line would be closed on Sunday the 18th, with RRBs running from Guildford to Surbiton and Guildford to Leatherhead.
But none of the RRBs ran, so no service on the New Guildford Line on Sunday the 18th.
I know there was another thread discussing the cancellation of RRBs on strike days:
If replacement buses are scheduled due to planned engineering works, and a strike is then announced for the day in question, is it a safe assumption that the buses will run as planned (assuming no unrelated problems like bus driver availability)? My particular journey is from Heysham to...

I can understand the logic of cancellation of RRBs on strike days - because if no engineering works were taking place, then no trains would run either.
But on Sunday the 18th, the cancellation of RRBs made no sense as it wasn't a strike day anyway. From tomorrow, there will be a limited train service on the New Guildford Line. This means that SWR can run trains on this line despite the action-short-of-strike. So they should have ran the RRBs on Sunday the 18th.
