award bases

[RadDad2005]

I've been away from the game for a few years, the answer to this question seems obvious, but I have a question.
Bases loaded, bottom of 7th (last inning), score tied. Batter walks to score winning run, but batter in celebration does not touch first and leaves the playing field. The defense throws the ball to first, ump calls him out, run doesn't count and off to extra innings we go. Seems correct, but is the fact that the base is awarded change anything about the batters responsibility to touch first? The runner on third was also awarded home with what was supposed to be the winning run (not relevant I suppose, but...).
I seem to remember something about awarded bases that might differ, but it's been so many years, I just can't say. I did not see this incident, the story was related to me. I think the ump did the right thing, but did he? Thanks.
