Maybe all Aladdin did was to send Emma to that world which is one of the other infinitve alternate worlds. But there's also A&E's comments about it being the wish created it. So, it's confusing. :P Yeah, the first part.

Genie magic isn't that powerful as to create an entire new realm at a whim. I think the wish simply poofed Emma and Regina, later, to a parallel realm.

So, you can travel within a universe, between universe, and in and between pocket universes.
