Umm. Depends on the distro, but this is configurable.  You can force users
to put in their old password before they can change it, or not.  See
/etc/pam.d/passwd (and the pam_passwd.so module README).  Note that there
is a facility for storing old passwords in MD5 hash in
/etc/security/opasswd so that you can't simply alternate between two old
passwords.
