Uhh... not so much. The Yozi were very happy to burn Creation to the ground, especially Malfeas - the point was just to have it back, no matter what state it was in. In fact, breaking it until it resembles Hell was basically their entire plan, because when there was no difference between Creation and their prison they could just come over all by themselves. Would it work? Probably not, but then I'm not an insane world-titan so what do I know?
That said, it still does make sense for them to have reality-repairing powers. The Outside is probably analogous to the Wyld more than anything, and, well, it was the Primordials that separated Creation out from the chaos in the first place.
