I have read the Handbook, thank you very much. The Handbook says, and I quote, "Originally separate domains, one similar to Earth-616 ruled by Iron Man (Tony Stark) and the other similar to Earth-1610 ruled by Nick Fury, the two accidentally merged when the latter's Tony Stark accidentally agitated a rip in reality.

This clearly states separate domains, not realities.
