  With the last 10 being retained, I don't think this one is
necessary.  And since it could prevent a leaked/compromised password
from being changed, I'd say it risks decreasing security rather than
improving it.

IBTD. Users tend to change their password ten times at once, then set
their old password as their new password, if you don't prevent them from
doing so. Also keep in mind that an administrator can change a password
anytime, so even if a password gets compromised, someone will be able to
change it.
