That doesn’t seem to follow, actually. You could easily have a very large universe that’s almost entirely empty space (which does “repeat”), plus a moderate amount of structures that only appear once each.
And as a separate argument, plenty of processes are irreversible in practice. For instance, consider a universe where there’s a “big bang” event at the start of time, like an ordinary explosion. I’d expect that universe to never return to that original intensely-exploding state, because the results of explosions don’t go backwards in time, right?

Yeah, nonemptiness was meant to be part of the assumption in the phrase you quoted.

We’re getting into territory where I don’t feel qualified to argue – although it seems like that objection only applies to some very specific things, and probably not to most Sleeping Beauty like scenarios.
