Time travel simply confuses me, but I was initially very confused by the organization disappearing after failing to capture sora as a vessel, but then my friend told me about a time travel theory of "anchoring" where you require the version of yourself in the present that you wish to visit, in order to stay there. And since sora as a vessel would have been the present xehanort, all of the other xehanorts would have been able. To exist in that timeline. I'm not to sure on it, but I hope it clears a few things for some people.
