Wolverine/Anchor Being Wolverine

Cause the post credit scene made it confusing that he was pruned from his Universe, but didn't confirmed which one though?

Because He said he will love playing Deadpool for the next 5-10 years like Deadpool 4. Also would Earth 10005 (The X Men Film Universe) get destroy at the end of Avengers Doomsday to paved the way for the MCU rebooted X Men Movies after Phase 6?

If the Wolverine of Earth-10005(B) is an Anchor Being, that would imply that had something to do with the Nexus event that created that branched reality.

What do you think was Wolverine’s nexus event?
