The splitting can be said to occur while they were separated, but
should we say that they were in the same universe they are revealed to
be in when they meet even while they were separated? It seems to me
that the Alice outside Bob's light cone who will eventually be
demonstrated to be in "same" world is just as unreachable, just as
causally isolated from him as the Alice in the "other" world. Perhaps
this could be dismissed as a mere philosophical point, but it does
emphasise that no FTL communication is possible or necessary.
