there were 4 schools, he never clarified that there were 4 followers, he likely lead Vale himself until he died and had a follower in line to take his place and give it back, just as Qrow delivered his cane.

That said, it may be possible he couldn't take over in his king persona, so he just put in a stand/in headmaster and pretty much ran it anyways, then gave the kingdom to the council upon death.
