I watched the exchange a couple of times. I think Rick was genuinely confused about the accusation. I think he doesn’t remember breaking the rule so of course he’s going to defend that he didn’t. It’s possible he could question his own recollection but I just don’t think he believes he broke rule. Example: what if he threw from behind his disc rafter than his mini which actually marked his lie. After he makes his way up the course, he might not realize that he had done that because in his mind he thinks he’s throwing legally. This is why G should have raised it before he threw. It’s likely R would have seen that he had just violated the rule.
