I got a theory. A farfetched one but a theory nonetheless, because such odd things have been known to happen. Could there be some sort of hack which somehow changes the name/info displayed to GMs? Example:
Non-hacker player is in the same map as the hacker player...
Hacker player can somehow change the appearance of their ign to that of the non-hacker player, and/or hacker can change the non-hacker's display of ign/info to that of their own character's.
I realize how unlikely this sounds; but if hackers can screw with skills/lag/dc, they can probably screw with all types of other things too, and this is one of those things. Maybe players do not see this in effect but only GMs can, that's why no one has reported on it or noticed it. But then again, I do not frequent hacking websites at all and there may be no mention of something like this in any of them.
