They had just completed a pass for 10 yards on the previous play. They weren't scrambling. Also, if there's one team who is completely fine going fast, who do you think that would be?
Remember, we got a sack on 2nd down. It was 3rd and 19. They completed a pass for 10 yards to set up the 4th and 9, it's not like they were running a Chinese fire drill out there. The literal play before the 4th down, they ran a play where they gained more yards than they needed on the 4th down. And their offense functions at warp-speed at all times.
My point is, Mario has made dumbass decisions that are clearly wrong (Hello, Georgia Tech). Where virtually any/every coach in history would have made a different decision. Clear -EV decisions. This was not one of them. This is purely a judgement call. Like calling or not calling a timeout in a basketball game down by 1 point with a few seconds left. Some coaches like to call timeout to set up a play. Others like to fly up the court and not let the opposing defense get set. Neither are wrong. There's no data that says one versus the other is right or wrong. It's just what you want to do.
