Great, except that most of the time, this collision DOES trap the trailing elbow behind you, which results in a a swing that's too much from the inside, an early release of levers, and a multitude of bad shots. The problem usually starts at address, wherein your balance is too much into your heels. Your body always wants to regain balance, so at impact, it moves to the toes and you instinctively raise up. This gets the hip moving towards the ball, which traps the arms. Thinking about more lateral hip slide will compound the problem.
Set up more towards the balls of the feet, let your arms hang so the butt of the club is measured at about your toe line. On the downswing, turn the hips out of the way earlier, making sure that your tush stays on the "tush line".
