I'd say Mags updated his helmet there somewhere off panel.Before that Mags was a telepath himself and/or was stated to have some sort of psychic powers, under Claremont he never displayed these powers and him resisting Xavier's attempts through his will power and psychic technology in his helmet. Magneto's powers were also shown to inhibit long ranged telepathy and managed to block Jean and Xavier in the first half of fatal attractions anyway.
In God Loves Man Kills a mind controlled Xavier(Again under Claremont) did mindblast Magneto's to the ground when he had his helmet on. Magneto just barely took the full blast with his helmet on and stated that Charles always held back in their previous encounters.(The helmet was knocked off after the blast and Magneto was weakened, he could barely move)Regardless Magneto seems to have updated his gear off panel since Morrisons run so he'd win since Ems best power is being blocked.
Brilliantly said, darling, as usual🙂
