To me, probability is observed reality, and the irrelevance of multiple identical/fully-isomorphic copies is a philosophical given. The state of our knowledge is certainly not large enough to disallow that conjunction.
Push me for details, and I’m less sure. I suspect that once you’re inside the 90% side of the wave function, you actually do branch faster; I’m certainly not aware of any mathematical demonstrations that this isn’t so, even within our current incomplete quantum understanding. It could also be that probability only appears to work because consciousness quickly ceases to exist in those branches in which it’s violated on a large scale, though there are obvious problems with that line of argument.
Anyway, if you accept these two postulates—one observationally, and the other philosophically—then the human’s logic works.
