Hmm... I'm not familiar with that but I know you don't need a second Xbox Live account, it just plays with 2 people using the same account with the additional player being a "Guest". But I suggest you try searching for your answer in the *Official* Xbox forums:

^Look for it there, I believe you'll find your answer or if not someone may know here. Good luck.
