Maybe `logic`ally, but not `human`ly.  ;)

For me at least, nested implies that to get to B, A has to be true: therefore B is inside A.

Otherwise it's simply a matter of prioritizing - LIFO, FIFO, random(), or whatever, and the only requirement to try the 
next is that the last did not meet our criteria.
