it takes a certain amount of weight to be able to descend quick enough to hit depth and stay tight. you can collapse and take any amount of weight down, but you aren't coming back up with it.
the pressure and strain it takes to maintain your positioning in the suit and under the bar increases exponentially when you take a squat to depth. Maintaining proper form and using the proper technique allows the weight of the bar to load into the suit more efficiently and drive your hips down quicker. Poor technique, positioning and improper form make it much much harder to descend to depth, with some people not able to ever hit depth properly due to technique.
the speculation on depth in this thread is kind of funny, andy is making no attempt whatsoever to reach depth in those squats, he's basically coming up when the suit binds up. At the point he's at he would need to push back a little more and drive his knees out to open up his hips, that would cause him to drop into the hole. I think its more like what J Byrd said, he's probably in a new suit. (although like i mentioned earlier, andy's depth is inconsistent at best, and generally squats a bit high).
