I can't see how you can describe it as being in the territory.

I probably meant that the fact that indexical uncertainty is unavoidable, is part of the territory.

You can't make a prediction about what exactly will happen to you, because different things will happen to different versions of you (thus, if you make any prediction of a specific outcome now, some future you will observe it was wrong). This inability to predict a specific outcome feels like probability; it feels like a situation where you don't have perfect knowledge.

So it would be proper to say that "unpredictability of a specific outcome is part of the territory" -- the difference is that one model of quantum physics believes there is intrinsic randomess involved, other model believes that in fact multiple specific outcomes happen (in different branches).
