I think you should look at an aerial view of the airport before accusing the OP of changing his story. It's quite apparent both of those "stories" can be true at the same time. It's your misunderstanding. This "turnaround" is not a run-up area. It's about 50 feet wide. That's it. It has no exits aside from the runway centerline. And at the end of a 3000 foot runway. A student pilot might be a bit low overhead after a T&G in, say, an overloaded 152. He should be able to full-stop in time, but a T&G takes MORE runway, not less, especially if the pilot isn't landing to ACS standards and does 1000 feet of student pilot floating.
The location there is rather vulnerable to other pilots screwing up. I'd be ticked as well, especially if I was on the centerline trying to backtaxi, or if I had my back to landing traffic.
