I'm surprised they expect kids to sit in kindergarten very long. Do you notice him falling out of his seat at home?
My DS used to fall out of his seat all the time. A lot of kids do. Especially if you fidget, especially if you are concentrating, especially if you are bored. And also if you don't have a solid integration of what you feel (gravity, friction on the seat, etc) vs reaction time to restore upright. Sitting on a ball or special cushion can help with these kids because it allows for them to be in constant motion, contantly getting the sensation of where their body is so they can react in time.
Most kids outgrow it as their mass increases and they get farther from the floor.

I don't know how long they expect him to sit at a given time but whatever he was doing was enough of a concern or just different enough from the others that they took steps. I am fascinated by your point about integration DS is very very thin. He does fall out at home but from my perspective it's related to how he starts - I have never seen him fall when all the way on the chair,legs in front, sitting properly. It happens when he only has one cheek on! Almost like he is planning an escape route. He also walks into walls, forgets to get off the bus. I suspect he is thinking about all sorts of other stuff - although he says no. He says it's because he want to get up and move around. He also said the other kids aren't supposed to watch him so he's not a distraction - he mentioned that today, made me a bit uncomfortable to hear him say it. I couldn't tell how he felt about it.
