Tiger carded a quad because he was pin-seeking from an incredibly difficult angle to pitch the ball close to the hole, desperately trying to get out of there with a bogey. There wasn't any wiggle room, he had to hit it perfectly near the top of the slope. He knew that, but still decided to play recklessly aggressive. Instead of a routine on-in-three and 2-putt double, he turned a 5 into a 7. It cost him an additional 2 shots.
Brandel might be correct in theory, but what if Tiger takes the penalty drop there, drops the ball, and it rolls out just enough to still meet the 1-club parameter, much nearer the hazard, but technically in play and now he can't take a stance? That drop area didn't exactly look level, if anything looked like it was sloping away from the walkway and toward the water.
Brandel saw it as an opportunity to remind everyone that he's smarter than everybody else.
