Alien X being the same across the omniverse doesn't mean that every omnitrix has Alien X, just that every omnitrix that can have a celestialsapien has Alien X.

It is, in my eyes, implied that Alien X gave their DNA (which is really more like a phone that calls Alien X TO Ben's position and then places Ben inside their physical mindspace. IMO this means the Omnitrix could then be used again) to Azmuth in multiple timelines and/or dimensions (or maybe just the one, we don't really know) as they wanted a voice of reason to help them settle debates. Night Stalker is correct in that Alien X is a separate entity as when Ben first used Alien X, Bellicus and Serena were arguing about saving the dinosaurs.
