I believe he *meant* "point" of entry (which is correct)
Funny thing. About 12 years ago I played in the DuPont World Amateur in Myrtle Beach. final round and the EXACT same situation happened.
On a Par 5 one of my opponents hit a sand wedge over a yellow staked hazard, hit past the margin of the hazard on the other side and the ball came back into the hazard, he, and another guy in the group said he could drop on the other side no closer to the hole. I told them no, he had to hit it over the hazrd again keeping the point where it last crossed the margin between him and the pin (or, of course, he could hit it again from the same spot) but he could NOT drop on the other side.
I'd had a few words with the other guy in a previous round. nothing serious but he was a Northern "Red-neck" and was pissed I was actually ahead of him after 3 rounds.
The point being he was getting VERY annoyed that I told him they were wrong. The guy that hit the ball wasn't nearly so bothered by it.
Anyway, I told him what he should do.
Play 2 balls, first declaring which ball he wanted to count if it was permitted by the rules. Then record BOTH scores and, after the round (or during if possible) have the Club Pro come out and tell him which was correct.
So he played 2 balls and of course he declared he wanted the ball OVER the hazard to count. He got that ball up and down for a 6. The ball he dropped behind the hazard he hit long and couldn't get it up and down and made 8.
It happened to be the 9th hole. As it came back toward the clubhouse, even though we had to make the turn right away we got word to the Club Pro who came out onto the 10th fairway and asked what happened. He correctly ruled that the guy had to hit from BEHIND the hazard so he took an 8 instead of the 6.
The HE got pissed off at me too. WTF ? After the round they both got hotter and I told him "So what should I have done ? Let you hit the wrong ball and be DQ'd ???"
