What does it mean? Why would you do this?

Depends on the way he is staring at you including the amount of time he takes staring at you.

He probably thinks your cute. But it doesn't mean they like you. They just like what they see. If you have the guts, try saying hi to him next time you see him. Eye-contact is so difficult, but if he does it on a regular base you can be sure it wasn't an accident and he was looking at you.
