Quantum superpositions splitting in MWI, or somewhat equivalently the fluctuation/localization of a decoherent event, can be amplified. In the case of this quantum suicide argument the lottery ticket numbers assigned may have a quantum basis going back in time. Within MWI this means the world split long before the winning ticket was announced. This has some similarity to Wheeler's delayed choice experiment. This means the splitting of the world is not a local process and we then have a question as to what are the prior probabilities for this splitting if we can't localize this event?
There is some sort of duality I think between local quantum fields and causal physics vs the nonlocality of quantum states. The only causal quantum field that may be intrinsically nonlocal is gravitation. Gravitation as emergent from quantum entanglements is likely a nonlocal quantum field. This duality then maybe be expressed as UV quantum gravity states = IR quantum field states which is a way of stating the Einstein field equation. UV means high energy near the Planck scale and IR means much lower energy say a billion times LHC energy and lower. The UV quantum gravity states are nonlocal while the IR quantum field states are local, or should it be said localizable.
