You're looking at this in too much of a black and white fashion. The arm is whipped around. The terminology is correct. Is it completely passive? Of course not. You're taking the analogy too far. You certainly use the arm muscles, but the salient point is that most of the power comes from the legs and the core whipping the arm around, not from the arm muscles contracting without the loading from the legs and core.
