More precisely, how would this situation arrise in the first place?

The allocation engine allocates a full block to a file, and does not 
allocate any additional ones until the present ones are full.

As noted elsewhere, in this case it's likely that the defrag partially 
corrected the freelists or something. (Remember, the filesystem was 
corrupted.)
