Yes but I'm confused, I though you were the one arguing that Bruno

That's hardly what Bruno is claiming. Step 3 is only a small step in a
logical argument. It shows that if our normal everyday consciousness is
the result of computation, then it can be duplicated (in principle - if
you have a problem with matter duplicators, consider an AI programme)
and that this leads to what looks like uncertainty from one person's
perspective.
You only get that impression because in Bruno's treatment of the case --
the two copies are immediately separated by a large distance and don't
further interact. You might come to a different conclusion if you let
the copies sit down together and have a chat.
Separating them geographically was meant to mimic the different worlds
idea from MWI. But I think that is a bit of a cheat.
