Ending Game

I have had to tip toe around the p**ing contest but this is what I've found so someone tell me is this correct or is there something else I am missing.

Dakota’s post is not quite the question that was posted. In Dakota’s post the runner made 2B and was tagged while off base. On page 70 in the NFHS case book 9.9.1 M.

In the last of the 7th. Inning, two outs. Score tied, bases loaded. B6 walks to force R1 home. B6 assumes the game is over fails to go to 1B and leaves the field. The ball is held at 1B. Ruling: B6 is out and the run does not score. (Rule 8.6.7 Exception b)

So B6 is out, run is nullified after the appeal?
