No, they say: "If you're connecting with -W to a server configured to allow you access via peer authentication you may think that it's requiring a password when it really isn't. And if the user you're logging in as doesn't have a password set or you enter the wrong password at the prompt you'll still be logged in and think you have the right password - but you won't be able to log in from other clients (that connect via localhost) or when logged in as other users."
