Saibal, I have to say that I disagree. As you acknowledge, erasing memory doesn't recohere the branches. There is no meaningful sense in which you could end up in a different branch due to memory erasure.
You admit the 'effect' has no observable consequences. But it has no unobservable meaning either.
In fact, other than what I call 'causal differentiation', which clearly will track the already-decohered branches (so you don't get to reshuffle the deck), there is no meaningful sense in which "you" will end up in one particular future branch at all. Other than causal differentiation tracking, either 'you' are all of your future branches, or 'you' are just here for the moment and are none of them.
