It's Claremont. In his later years, he'd start building up a lot of plots that didn't wind up going anywhere, but in his prime, the dude was a continuity machine. I don't think the idea of handwaving the events of another comic ever even occurred to him.
Besides, this entire scene isn't so much an attempt to fix things as it's looking at Jim Shooter and saying, "What the fuck are you doing to my character?" He gets attached to superheroines he's written.
