That rule's intention was to penalize someone for burning a second off of a close clock in order to end the half or game with a FG and time expired. It explains it quite well. It absolutely is not a rule that should be applied when there is 30 seconds left on the clock and there is no advantage to burning 1 second more off of it. It's what they call "a situational foul". This situation absolutely did not call for that penalty. And, even when they did use it, they only used the portion of the penalty that they wanted to, not all of it, or else they would have run 10 seconds off the clock, according to that rule.
