Even without that story, in OMD itself Mephisto implies that taking the marriage is just step one, to eventually get Peter's soul in a way Mephisto would prefer:

That's not how it happened, as TOAA only says that Peter has worth since he saved so many people, and to have faither, it's Sensational#39 that implies this when Peter talks with aunt May via Madame Web.
Like I pointed out before, Sensational was surprisingly optmistic right before OMD, issue#39 has aunt May telling Peter trying to accept she's going to die, issue#40 has TOAA talking to Peter so he tries to have faith, and the Annual has that story that is at its core "Peter and MJ love each other very much", I'm pretty that reading that, then going directly into OMD, only made the impact worse for people who read Sensational.
Spider-Girl happened in a world where Peter retired during the Gathering of Five, and I think the "May" they found was Mayday instead of aunt May, so yeah, the big change happened a lot earlier, and OMD never happened there, as Peter's secret identity was still a secret.
