I actually think the subordinate tom is just waiting his chance....waiting as close buy as possible. I once shot a tom out of a group of toms during a fall turkey hunt in NY. As soon as he started flopping another tom attacked him. The one I shot had behaved like the boss but "his buddies" were just waiting for the opportunity to eliminate their "brother". I think they are so instinctively programed to reproduce they stay as close to the hen (opportunity) as possible.
