You are simply forgetting that the crash may occur for a completely 
different reason than power failure, for example crash of the kernel.
It occurred to me once that i removed sound module from my freebsd box 
which paniced immediately. Unfortunately this may have been in the middle
of updating the superblock and at reboot fsck was unable to correct the 
situation and asked for a copy of the superblock. Still more unfortunately
the first backup was corrupt also, and i had to find another good one.
