password

In implementing a GPO for Active Directory, a colleague has mentioned that they have implemented one which disallows 'similar' new password to be chosen - i.e. 'password1' cannot be changed to 'password2'.

Seeing as AD stores all passwords as hashes, and a hash of the two options above would be markedly different and certainly not related - how can this be possible?
