Yeah, Visconti just tried to pass on the wrong side. He has nobody to be angry with other than himself. Ulissi drifted a little, but nothing out of the ordinary or dangerous. Of course the guy in front isn't going to let anybody pass on the barrier side. Petacchi's move on Stage 2 was a lot worse and he didn't get in trouble for that.
Visconti should be kicked out of the race. Imagine if Cav had done something like that. It's a good thing Lastras was paying attention or that could have been ugly.
