Thing is about the way DOFP ended everything from 1973 didn't happen as seen in the first 4 movies and the Wolverine. So the current time is First Class and DOFP and nothing else because it was all undone by Wolverine going back in time. Hence, the reason why Jean Grey and Cyclopes are alive at the end of the movie and Professor X and Logan are the only ones with memories of the alternate events.
