Yeah I guess that makes sense. I am kind of suprised that they dont hand out different tests on the same day to avoid cheating. I never asked if we had the same test that day I just assumed they mixed it up like they do in a lot of undergrad classes and at the DMV.(DMV is a bad comparison I know)
The sections are in different order for different people, and the experimental section could be LR for one person, RC for the next, etc. Plus, I think anyone looking to copy answers from their neighbor probably isn't going to score that high in the first place.
