Only display alternate names of connected accounts if they are not equal

I'm a little bit confused about the double displayed names on gittip, where the nickname is equal to the real name (twitter for example).
I think if the nickname is equal to the real name, the bracketed name should not be shown.

So "Santina4r3 (Santina4r3)" becomes "Santina4r3" and "whit537 (Chad Whitacre)" stays "whit537 (Chad Whitacre)".
