It's not confusing at all. Just kinds backward thinking. He's still a junior eligibility wise. The only reasons your logic would matter is if they only let him play college for 3 years because of his age, or if you think he will peak before his senior year.
Uthoff was a year older than his class and look at how much better he was as a senior than as a junior. He was probably still better the year after that, which would have been his senior year if he had the luxury of being a year older than his high school class like Pat is.
