Well... the explanation is: just because.

I asked something similar about Earth-96283 back then, and there's no other explanation but "because the handbooks say so".

What we do is just ignore some continuity errors and take some things as retcons, like A.I.M. in the Iron Man videogame and in Iron Man 3.
