correct me if I'm wrong,
the fact that on the flop there is a third caller (who in fact acts before UTG+1) plus the club on the turn gives UTG+1 the proper odds to call on the turn.
if the same cards falls on the turn but on the flop there were no additionnal caller he wouldn't have had the odds to chase me.
