The big difference with golf is that pool is not a whole body movement swing, really only the break shot is and that's when I look at the cue ball. You are in position for a long time before pulling the trigger shooting pool and making relatively serene movements compared to golf. We don't look at the dart last when throwing darts, or the football, basketball, baseball, etc., we look at were we are sending the object. I think with golf and while at bat playing baseball the main goal of the activity is the ball strike so we focus on the ball, when we throw or shoot something the main goal is where the object is going so we focus on the point we are moving the object to. To me looking at the cue ball last is equivalent at looking at the tip of your rifle while target shooting.
