Yeah, it happens in some cases that to certain character which comes from other universe to X universe, we give him/her the designation of the X universe.

Examples are Rachel Summers (Earth-41001), Talia Wagner (Earth-41001), Lucas Bishop (Earth-98193) and both Death's Head (Earth-8454) & Death's Head (Minion) (Earth-8454) (thanks KalKent for the examples list).
