buggy openid login

1)My main account is registered with an openid. When I try to login with the open id, bitbucket acts as if it hasn't seen the id before and asks if I wish to register or associate it with an account.

1. I give up and use another account with access. This account uses a normal uid and password. When I try to login with this account, bitbucket logs me in to my openid account (the first account I tried).

I assume the security works, and this is just a bug in the ui?
