[Mass Ump]

I thought according to Rule 7 Sec 2 D 2 b. EFFECT b. Any advance of runners and any run scored shall be nullified. All outs made stand. I know that the umpire made a mistake because of the ruling that NCASAUmp gave ASA 3-6-D.
But I thought if it was the incorrect batter that you would take away the run because it was the last out of the inning and even though the batter struck out the batting out of order was discovered before the infielders left fair territory. I thought it didn't matter which pitch it was to the batter, the run scored on a pass ball two pitches prior to the strikeout. It doesn't state in the rule book that the batter has to become a batter runner it states After the incorrect batter has completed a turn at bat. Any replies will help with my thought process.
