We've discussed this before, many times. If S's equation represented a
horse race, with probabilities changing during the race -- of the order of
final results -- why do you think the race continues in other worlds, with
all combinations of outcomes? I think you egregiously misinterpret what S's
equation is telling us.  AG

Many Worlds explains why that, although from the multiverse point of view
