Intuitively, I see things the same way. Enho and Tochinoshin were rocking and rolling right up to the threshold of their respective goals, then seemed to weaken in astonishment.
However, I think sports fans in general put too much stock in the ordering of probabilistic outcomes. Tochinoshin is 9-3 after day 12, and the consecutive losses make him look shaky, but what if he lost on, say, days 3, 4, and 8? He'd have the same record and be in the same situation looking for his 10th win, but we'd probably come up with a narrative that said he had a hard start at 2-2, but then showed mental strength and determination in steaming his way to 9-3, and surely with a 10th win to come.
Unless the change in performance is due to injury, losing on days 11 and 12 isn't any different from losing on whatever other days. 9-3 is a good spot to be in for him.
