I watched 6 different bucks involved in 4 separate little "tussles" in Nov. last year in one sitting. I've even heard of small bucks and does squaring off.

I think it's just something they "do". I don't think (and I admit to not being any type of expert) they're "really" "fighting".

It was comical to watch the little ones I saw "sparring". They looked clueless. No experience seeing them do it any sooner (personally). Great catch on the trail cam.
