This may be a problem stemming from the amount of people learning to climb in gyms (pure speculation). The reason I think this, is because a lot of gym's rental harnesses just have the 1 hard point and they are taught in the classes to orient the braking side of the rope towards their brake hand (left/right). Then, when they buy their own harness or borrow a friend's with a belay loop, they try to orient the brake side to the left or right, as opposed to up/down, sometimes resulting in the brake side comming out the top. I've seen this happen quite a bit, but if their brake hand goes down to the side quickly, I have no gripes.
