The Cessna is only required to stay above 500 feet so he could be anywhere from a couple hundred feet below, to a 1000 feet below.
The pilot is required to provide clearance based on several factors, one of which is the amount of human congestion below. If there is little or no human activity below, he may fly at an altitude which provides safety in the event of engine failure (i.e. no specified minimum altitude, but he must be high enough to make a successful landing if the engine fails). If there is a low density of human activity or construction in the area, he must fly 500 feet above it. If there is a congested area below, he must fly 1000 feet above it, or 2000 feet horizontally away from the area or obstruction. These requirements are contained in USA FAR Part 91.119, which governs flight activity.

Actually a Cessna trainer can do some serious banking. I've been in banks that I thought were a lot farther than the aircraft was rated for, and came out of them no problems. I flew 172s when I was younger. You can bank up to 60 degrees legally, per the FAA before you're considered in acrobatic flight, but a 172 in an uncoordinated turn will pull 90 degrees, and easily pull 50 degrees in a coordinated turn. I've been up to 55 before when we were learning about G effects in a small aircraft.

You can't do a COORDINATED 90 degree turn, but you CAN do an uncoordinated turn at 90 degrees. I know a few people that have done them. You can't do coordinated turns much past 60 degrees in a 172. But if you aren't after pretty, or if you want a low G turn, and you have the altitude, why not do an uncoordinated turn?
