So maybe this is a little trollish but the definition of two boxing is vague enough that I can't help but ask.
Would the following player be considered 2 boxing if they were playing on P99?

TLDR: One of them controls one side of the body, and the other controls the other side. So they would have to both be dual boxing, technically, if using mouse and keyboard... or be able to play with one hand.
