@George,
Whether it is a Multiverse, or a sequence of Universes where exactly the same thing happens, that is, all those possibilities of arrangements that can exist both of atomic combinations and law variance in each big bang out of quantum foam in the frozen sea of particles in the far dead future and that end up happening in a close loop of finite information combinations with a rational limit, without infinite regress and infinite diversity of information...well is not important which is which...time being relative and irrelevant, one might indeed grant they all are an ensemble. Be it the Multiverse, be it the sequence of Universes in a specific spacial order that also happen to be a timeless ensemble in spite of the position ordering. The difference is so small that one might attribute the problem to bad conceptual imagery about phenomena as space and time.
