If you want to make the duplication machine stuff analogous to the MWI then at some
point you've got to recombine the Moscow Man and the Washington Man back into a single
entity that has memories of both cities. When a single electron is at the 2 slits the
universe splits because the the electron went through slot A in one and slot B in
another. But after that when the electron hits the photographic film (or a brick wall)
there is no longer any difference between the 2 universes so they recombine but the
information about the slots they went through is retained and this produces the
interference pattern.
But, according to MWI, there are universes in which the electron "recombined" to hit a
different spot on the film. MWI postulates that all outcomes of an experiment occur,
whether they involve interference effects or not. Even if you just had a beta-emitter and
you exposed a photographic plate to it long enough to get one spot, that spot would be
different in the different worlds of MWI. And in those different worlds the experimenter
would win or lose bets on where the spot would be seen.
