Golf Logic

I went to a wedding yesterday. The reception wasa at the "Three Rivers Golf and Country Club". During a lull in the proceedings I took a stroll to the first tee where I found a large sign-board with the rules of the club painted up for all to see. They must have been devised by a professor of logic because, apart from all the expected ones about not using buggies in wet conditions or in certain areas, there was this interesting request. "Maintain your position on the course by keeping your place directly behind the game in front of you, NOT directly in front of the game behind you." Unless you happen to be the last game of the day, I can't see how you can do one without the other being an automatic corollary. Maths much have changed since I did it at school! - or perhaps I've just never understood the rules of golf (which must obviously supercede the normal rules of logic for those concerned).
