That's entirely possible. But apparently, even the book considers they're from different timelines/universes, as seen here (preview for issue #22.NOW).

In Beast's drawing, Timeline 1 would be Earth-TRN240, Timeline 2 would be Earth-616 and Timeline 3 would be the future from Battle of the Atom whose TRN I can't remember.
