My speculations are, he'd be committed right now if ND wanted him to be. (and maybe he even is silently)
I think Dante would have said "I'm in" but I think he told the staff he still wants to be sure. The staff told him the no commit/visit policy and told him to take his time committing and that his spot will be going nowhere.
And honestly, I think that's great. That avoids the Rhett/P Bowen situations were kids get that itch to do it anyway. That's when temptation can lead to going behind staffs backs etc. That's where things get really messing.
Of course a commitment and shutting down visits is ideal, but that is not always going to be the case. I think if a kid really, really wants to be sure, then wait. And I also think (I do not think this is the case) if Dante is doing all of this to go on tour for fun / brand / follower building, he can do that too. It's his choice, and financially it's honestly probably wise on his part if this is all pure fun for him on a personal level. (again, I don' like it, and not ideal for the class, but a las).
