It sounds like a miscommunication between you two, nothing more than that. I would view this as a blessing though. For me, interviews are a chance to evaluate how well we can communicate. If I can't be relaxed, make jokes and just feel free to talk, then I won't feel that way working for you during the next year, and that to me, is a no go. I'd say indirectly you dodged a bullet, sounds like you two might be a high risk for constant miscommunication.
