It didn't apply yesterday because of the immediacy between the offside and (foul) by Pickford .
But had there been ssy a five second interval pulling the decision instantly would have prevented Van Dykes injury IMO.
So letting it progress could have unintended consequences.
Not the smartest rule IMO.
The idea is that if the linesman flags immediately and play is stopped if VAR shows it was the wrong decision you can't go back. If they let the play conclude and then flag if VAR shows they were wrong any goal scored can stand.
