Depending on who you ask, "alternate universe" and "alternate timeline" are interchangeable terms. Since the spell was programmed to drag Twilight and Spike back to the present after a certain amount of time, it's possible they would have continued to exist and taken the place of their alternate selves in order to prevent a paradox.
