SP:  We can imagine an external observer looking at two model universes A

DN:  Yes, and my point precisely is that this is an illegitimate sleight of imagination where the thought experiment goes amiss.  When one imagines the 'external' observer 'looking' at two universes, one constructs precisely the false relationship that is the source of the confusion with respect to consciousness.  Any possible observer must in fact be integral to their own universe.
You can look at the Game-of-Life-Universe, where you can see how the "gliders" move.  If you look at "Conway's game of Life" in Wikipedia, you can look at how the Glider Gun is working in the top right corner.  This is possible although there is no observer integral to that Universe.

The same is true about the B-Universe.  You can look at it as an outside observer.
