It's a analogy of a very boring experiment in which there are two possible outcomes where there is no way even in theory of ever knowing more about those outcomes; for example sending photons through the 2 slits but removing the film and letting the photons travel for eternity into infinite space after passing the slits. And interference is a part of our world of vital importance that needs an explanation, so that means if the people are not allowed to merge back together as well as be duplicated then Bruno's thought experiment is NOT a good analogy for the Many Worlds Interpretation or of Quantum Mechanics in general. It works fine for Newtonian Mechanics but the fundamentals of that are so intuitive that we really don't need an analogy involving copying machines to figure out what's going on with Newton. And even if you allow the people to merge it should be noted that the analogy is between the people in Bruno's experiment and the photons (or electrons) in the 2 slit experiment and not with the people performing the 2 slit experiment, the photon (or electron) has a "memory" of it going through slot A AND going through slot B but the people don't, all they see is a interference pattern.
