The article starts out with what we know, but then talks about NBA scouts and the NBA scouts want him to attend college. Probably this one of the reasons for him suiting up 2nd semester.

At that event, most NBA scouts said they thought Diallo wasn’t yet ready for the NBA and should attend college.
“Based on what I saw tonight and this summer he should attend college and continue to develop his game,” one NBA scout said. “He’s athletic and flashes some skill but has a ways to go from being NBA ready. I think someone would draft him for his talent but it’s not about making the league, it’s about giving yourself the best chance to stick.”
“[The NBA scouts] were disappointed by the lack of urgency that he showed,” Jonathan Givony of DraftExpress.com said. “He was kind of going through the motions and coasting. His jump shot still needs a lot of work. His body needs a lot of work. If Hamidou is not going to play hard, then he’s just not that interesting a prospect. He’s 6-5, 190 pounds without a great jumper. You can find that a dime a dozen.
“What I loved about Hamidou before that with USA Basketball, on the AAU circuit, Adidas Nations, every time I’ve seen him play, he was always playing harder than everybody else. He was a monster defensively. He seems to kind of have backed off of that a little bit and that’s not a good sign for him. I think he’s a much better prospect than what he showed, but when NBA guys come to evaluate you and you turn in that kind of performances, they might not come back. So he has to be thinking strongly about college at this point.”
