I think the "three" straps are the cam, quick release and a third lightweight adjustable strap - I use the latter to quicky position the BC and tank - adjust the length of the strap so that it becomes tight when the strap is slipped over the tank valve and pulled tight as the BC is pulled down to the correct position on the tank. FWIW, I replaced the quick release strap with a regular camband threaded through the next lower web slots on the back, allows keeping the BC a bit "higher" on the tank to keep the valve away from the back of head. The second band also keeps the tank steadier and reduces, IMHO, the possibility of slippage.
Good diving,
