There is not much you need to learn here. It is very simple.
OS X v10.8+ (-m 7100) uses PBKDF2, which allows to have a variable output (digest/hash) length.
oclHashcat doesn't care much about this hash length (it could be very long, or just the minimum length), but the only thing to know is that given the same password and salt you will end up with the same hash (which you could extend in length or not).
But why would one care about the length, if oclHashcat did find the correct password and hence the hash was cracked everything is fine. So why should/would oclHashcat try to distiguish them if they are identical (except the output size)?
