Appeal question

FIRST, this applies to "leaving early" on a pitch, NOT "leaving early" on a caught line drive or fly ball.

This is incorrect. Runners may only advance as far as they are "pushed" by a batter's clean hit. On a HR, for example, they all score.

The only "no runner may score" situation is, with the bases loaded, the batter hits a ball within the infield and no outs are recorded. In that case, the runner on 3B is removed from the bases without scoring and the others advance one base.

For leaving early on a line drive/fly ball - same as OBR - appeal required.
