Based on my reading of everything Bendis wrote regarding Magneto in Marvel-616, I have come to the conclusion that what BMB intends is that Xorneto was a fusion of a dormant & sleeping Xorn + unaware & unknowing Magneto (ala Darwin + Vulcan) because Magneto needed another extra power source again (ala Fabian Cortez) after surviving the Genoshan Massacre, and Xorn needed a physical body after turning into pure energy (a star for a brain, after all), and that Magneto went crazy after taking Kick (Sublime's aerosol form) which caused Xorn to wake up and confront him in his own mind, and that after Wolverine beheaded Magneto, Wanda resurrected him (ala Pietro) and had him relocated to Genosha as was suggested by Dr. Strange.
I think that even Chris Claremont may have even been in on it, as the coffin supposedly containing the corpse of Xorn which Charles brought to Genosha was never shown to actually contain an actual corpse, but was shown instead to contain an entire collection of heavy-duty high-grade firearms and ammunition. And Magneto mysteriously developed the new limitation of having migraines whenever he exerted his powers beyond a certain shockingly low threshold. And Magneto was so friendly to Charles, too friendly, as if the entire decade of the 1990's (and all the Xmen vs Magneto stuff written by Lobdell, Nicieza, Kelly, Seagle, etc.) never happened at all. And Magneto later rescued Wanda from the Avengers using the creation of a wormhole that previously only Xorn was shown as having been able to create, and he rescued her using the VERY SAME EXACT COSTUME he wore in Planet X.
Read the following stories in order then it will all make sense: Avengers Disassembled (Avengers Vol. 2), Xmen: Deadly Genesis mini-series (By Ed Brubaker), Planet X (New Xmen), Here Comes Tomorrow (New Xmen), Excalibur (the Genoshan volume), House of M mini-series, The Collective (New Avengers), Matthew Malloy (All-New Xmen).
This is the only theory regarding Xorn and Magneto that makes perfect rational and logical sense because it relies wholly and purely on what was actually shown on-page from Marvel over the last 15 years from 2001 onwards.
