But if both erase that memory then there is no longer a difference between the 2 universes and thus they merge back together, but the fact that they were once different means that interference effects will be observable. People always talk about the universe splitting but they can merge too, although that only happens if the difference between the 2 universes is very very small because if its large you’re never going to engineer things so they become identical again. That’s why we can do the 2 slit experiment with photons and electrons and even with buckyballs made of 60 carbon atoms, but we can’t do it with bowling balls, the difference between a bowling ball going through slot X is just too different from a bowling ball going through slot Y to ever make the 2 universes identical again so they can merge back together. We can see interference effects in a ball made of 60 atoms but not one made of 6.02*10^23 atoms.
