That is technically theoretically true, but it isn't going to happen on a relatively normal pit. As I said, over 50+ feet tall...unless it is super wide, as in feet not inches.

It only takes a very small temp difference for the air to keep rising and there isn't enough heat loss in a chimney to get from 200+ down anywhere near ambient temp.
