[X-Men Days of Future Past] - What happened to the mind of the alternate Wolverine who lived through the new timeline?

So in DOFP film, Wolverine goes back in time and changes the past, effectively erasing and altering the timeline to a new one. 

Now he wakes up in 2023 with no idea what happened since 1973. 

But surely in this new timeline, Wolverine did eventually meet the X-Men and have new adventures with them. He was after all, teaching history at the school. So did this version of Wolverine just cease to exist once the original timeline one woke up? 

My guess was that Charles restores his memories. And by the events of Logan 6 years later, it is implied he does remember such adventures (hence his commentary on the comic books, saying that they're only partly true). Am I correct in assuming that Charles restores his memory and he vas memory of both timelines? Cos that makes Logan an even more tragic film, he has to watch his friends die twice.

It doubt it would be possible to restore such time-tossed memories, which to his current consciousness, he never temporally experienced.  To do so Prof X would need to be able to transcend linear time in his telepathic abilities; reading a mind in the past and copying from it.

Professor X *can* implant the memories of everything he has seen Wolverine due (complete with the mind-reading of his surface thoughts and emotions.)  As well as the more physical memories of others.
