I don't know what was said. When I offiicated, if the wrestler said a few curse words after losing a match I could live with it if i) it wasn't directed at me and ii) it wasn't so loud that everyone in the place heard it.

If the cursing got him 2 unsportsmanlike conduct calls one after another it must have been pretty abusive...the official could have looked at it as one continuous act...which would not have resulted in 2 UC and the DQ.

My guess is, and I think it was implied above, that the official may not have realized that two UC calls after the match was over results in a DQ. If had been during the match it would have been just a couple match points, no big deal. After the match UC doesn't happen very often...and no one likes to see a match/career/season, end this way.
