I can confirm this as well. Personally, I prefer this with that reset trainers script so I can reset the gym and not fight them. The two pokemon worth killing in the gym are Beedrill and Scyther being 557 exp and 450 exp respectively. You simply fight the back left corner, the middle, and the leader. (I'd ignore the middle too but there's no way around him.)
The other trainers in the gym actually aren't worth having at if you can just reset the whole place. I guess that's the problem with being able to reset gyms and trainers, though. Trainer battles become.. not as valuable as they were before. The phone system really helped, but it didn't scale to you.. A guy can dream for nice things.
