Single click registration should override FB registration form

I have "Allow users to register with Facebook" and "Allow single-click registration" checked in Facebook Connect settings.
On the wp-login screen, the "login with facebook" button works as intended, allowing a new user to register a new account and login using their Facebook account. However, on the wp-signup page, there is a different "register using Facebook" button that takes them to a form. My intention is to have single-click only, since it can handle both registrations and logins. I would like to suggest that the single-click option, if checked, overrides the registration form and takes the user straight to facebook to connect.
