The problem here is that we are talking about two different concepts - experienced moments (as in antophics) and Everett branches (as in Many Words). There is a way to think of them as the same, but they not necessary are. Like if there is Bob before measuring spin, and two Bobs - Bob-up and Bob-down, after measuring, what is bigger probability to experience - being bob before measuring spin or being bob after measuring spin? (TBH I have no idea)
