I mean, it coexists. It's just contradictory.This actually doesn't coexist with DOFP, as the ending of DOFP is set in a future where new mutants should have stopped being born, yet we see young mutants running around the school. Wolverine mentions no new mutants had been born for 20 years, so they should have stopped being born in 2009, yet the end of DOFP was set sometime in the late 20-teens I believe.
So, long story short, they're two different cannons.
