There's no dodgy metaphysical mechanism involved. If there are multiple physical copies of you, and each copy has a similar consciousness to you, then you can't know which copy is currently generating your consciousness. I think the idea is that the "stream of consciousness" is unified so long as all the copies are being realized identically, in fact they are not "multiple" per Leibniz's identity of indiscernibles. When there is some quantum event amplified enough to make a difference in the stream of consciousness then the stream divides and there are two (or more) streams. An implication of this is that if one of the streams terminates your consciousness will continue in the other.But it will, at best be *similar* to the deceased "you", just as I am quite different from Brent Meeker of 50yrs ago. And there is no quarantee that some stream will continue. Type 1 multiverse normally garantee not only similarity but exact match somewhere....
I think it only guarantees an exact match (and hence only one history) up to the last quantum event that got amplified to the classical level before you died. I don't have a very good feel for the time scale, but it seems that could be a few minutes. And in anycase, dying is not sharp, well defined event.
