Due to the fact it is an admin tool, it is probably a bug, as if it was supposed to be infinite it would give you an infinite amount of paint.

Though it really isn't worth fixing, as only admins will ever notice and it is a handy feature. Admins are mature enough to live with a glitch in the numbers.
