Usually because you only need access to one at a time. The OP mentioned a 
stack just for frame pointers; I assumed (perhaps wrongly), then access to 
any of them might be needed at any time. If not then a single stack will do. 
(Or perhaps no real stack at all, as a software data structure seems to be 
used. Then, any scheme could be employed.)
