While not convinced by the statistical argument either, I think a more accurate analogy would be "Imagine you have a cell. It breaks apart into two identical cells. [Rinse and repeat a bunch of times]." And then if you pick a cell at random from the resulting set, it is indeed more probable that you picked one that is not the original one. IMO this doesn't apply as cleanly to simulated universes because they're not literal clones of one another, plus we're not even sure it's even possible to simulate one (while we know cells do go through mitosis).
