it sounded good until you got to the middle of your explanation. here is a corrected version of yours....
basically, the camber of the ski, is the way it bends when under no stress or force.
if you were to put a pair of gs, slalom or park skis (regular camber) on a table, the tip and tail would touch the table, but the middle of the ski would be in the air. (creating an upside down u shaped gap between ski and table)
A reverse camber ski, such as the old Volant Spatula are the exact opposite of this. So in other words, it is a perfect curve, but just in the opposite direction. So only right underfoot will be touching the ground and it will bow up on both sides of that. the problem with this is that when skiing, you have no running length on your skis, therefore ski companies have turned away from this method.
A rockered ski, such as the hellbents, pontoons, EP Pros, ARGs, Seth (mini-rocker) and ETC. are flat underfoot and have the tips and the tail raised at a certain point on the ski. This idea is also used on wakeboards and surfboards. This is much more versatile than reverse camber simply because of the running length which is always in contact with the snow. Therefore pretty much all skis you will see on the market today which you may be tempted to call "reverse camber" are in actuality "rockered".
