TEPaul,
Most of the ones I've played penalize a ball coming up just short, making the ball back/roll off the green and leaving a nasty putt, so I think that they were designed with tactical significance, and not to aid the golfer.
Hollywood has some severe ones on the 6th and 10th holes and a few subtle ones as well.
My GUESS is that with yardage markers dialed in, the player is less apt to rely on his vision, and the false front was designed to play on ones vision and present an optical deception, but, that's just a guess.
If you get a chance to play Hollywood, don't miss it, with the GAP's radius of 150 miles, you can easily claim it as well.
