I don't know how Pizzuto works, but if I wanted to lead from the pole I would probably be telling people "Hey I've drawn the pole and I'm going to lead so back off". I wouldn't want to give them a sniff that the lead is there. Maybe he giving them a sniff so he can take a sit, thus put Bull out of the race and hope a gap appears (which is likely over 2900m if Lazarus or even Soho setting the speed) coming into the straight?
