This wouldn't be the first time JMS screwed up on continuity issues during his run on Amazing Spider-Man:
*More than once, he has depicted the moment that Peter Parker being bitten by the radioactive (and magical
) spider happened during a class field trip (he went by himself to the science exhibit) and that Harry and Gwen went to his high school (when they did not).
*In order to make Aunt May feel guilty about the death of Uncle Ben, he had Ben leave the house after an argument, then, when on his way home, is shot just before entering the house; however, there have been several issues that have shown they were together when the burglar shot Uncle Ben.
*A few times JMS points out that Peter never tried to profit off of using his powers, completely disregarding that Peter started out as a
wrestler/entertainer in order to
make money (although it was mainly for his Aunt and Uncle), not to mention photographing his own exploits as Spider-Man and
selling the photos to Jameson for money.
*And the most blatant retcon was having
Gwen Stacy awake and fully conscious when the Green Goblin
physically throws her off the bridge; in reality she was unconscious and was knocked off when the Goblin Glider hit her.
All of which could be easily checked out and verified through some of Marvel's own publications, considering how often the origin story and the Death of Gwen Stacy are reprinted. Why then should we be surprised at him screwing up a character's name?
