I think the point is supposed to be this:
-Fett is not named in TESB
-Fett IS named in RotJ
-Some people would like Fett removed from RotJ...
which means that he will never be officially named in the films, which he was originally. Making it semi-reasonable to ask that his name be said on-screen in the one Revisited film he does (in this scenario) appear in.
