That's one of Butch Harmon's tips for Winged Foot in a Bill Pennington New York Times story. And this is an interesting observation about the tiered rough, and one some of us have been trying to explain is yet another reason that pitch out rough is absurd:
"Guys who hit into the long stuff will wedge it out and take their bogey," Butch Harmon said. "The actual danger is the second cut of rough, the stuff that's three inches deep and three yards from the fairway. Some guys will be tempted to go for the green from that stuff, and that's where the double bogeys will come from."
