If M is the "real" one that would also explain why Takaiwa is his suit actor and not Emu's. It'd make sense.

That being said, I'm with Fish Sandwich in thinking that revealing the alternate personality to be just this total foreign entity would really devalue the character. Which is why I'm hoping they're going for a little bait and switch. Like, making us think they're distinctly different, but then go with some other explanation like...yeah, the second personality came from Bugsters, somehow, but all it did was enhance a side of him that was already there. Or like, maybe those 16 years have really made them one and the same in all but manners. Because like, they do act different, but they're still clearly the same people. They have the same goals, the same feelings, the same morals and...you know, stuff.

And probably I'm just reading too much into this, but I do think that's what this episode was kind of hinting at or showing. When he first splits up into M and Emu, it's like they're fighting over who is the "real" one, but the second time, that doesn't really matter. "You are me and I am you." Kind of expecting that to be the whole point of this second arc and Double Action in general.
