In the case of SSH login, you are correct that the hash is not used to 
login.  But the attacker may find a way to read the hash out of the 
/etc/shadow file, or the same password is used in other places and also 
stored with a md5 hash.

A lot of things would have to go wrong for a remote attacker to get 
access to /etc/shadow - but it's been known to happen.

(Personally, I always move the SSH port to something other then 22 and 
we only allow authentication via public keys over the external port.)
