Exactly right. I remember a cup game where it had gone to extra time, but the away team had scored twice in the first half of extra time and again at the start of the second half (after an uneventful 1-1 draw in regular time!). Second half is coming to an end, their striker is through on goal, taps it round the keeper just outside the area and is taken down.
I decide that he wouldn't have reached the ball before it went out of play, so issue a yellow to the keeper because it's therefore not DOGSO. Would I have reached the same conclusion if the game was tight? Hard to say...
