I've just been using same to check how come Pete Wisdom pretty conclusively died in a comic I just read from 2000, but then still appeared in possibly my favourite new superhero comic of the past few years. Its answer was distressingly vague.
(Said 2000 comic also had an X-team based in San Francisco, and an event which had caused all mutants to lose their powers. How things change, or not - I'm not so much surprised that Marvel repeated this as that no fans I know have pointed out the repetition)
