I bring this question up because you repeatedly refer to only "one Alice" before the measurement, and also say that Alice and Bob are "in one and the same branch" prior to measurement. But normal QM without collapse would say Alice and Bob are branching all the time, even before they measure their entangled pair. So isn't it necessary to take this into consideration (that this is implicitly the original scenario):
There are many branchings of the wf describing Alice, almost all of them are irrelevant to who Alice is. They are below the quasi-classical level at which "Alice" exists; below the level at which her brain decides at what angle to measure the particle. All those Alices are one person. So they are treated as one classical being. That they split into two (up or down) classically distinct beings, is unrelated to the fact there are many microscopically different Alices.
It is not clear to me how Bruno thinks of these many quasi-classical, Alices. He seems to just dismiss their differences as below replacement level the Doctor promises. That seems like assuming that they are really classical entities, just similar computational threads in the UD.

There are many Alices, and many Bobs, and depending on the experimental setup, many measurement angle choices?
