If you properly read X-Men the End you'd know that is not possible. Everything up to ReLoad was the same. The divergence clearly occurs a little after Reload. I'm thinking it's HOM, in their world HOM didn't happen and so, the ReLoad teams continued and well that's where they'd be 15 years from then. IF the birth of Gambit was different, then a lot of other things should be different. Until that is cleared in 616, we have to accept it.
