This is a behavior Han is going to see a lot more of if they continue to get to know each other. It's a fantastic way of throwing someone off-balance, even if they're a strong-willed opponent though Lizzie seems immune to it at the most inopportune times. He's by no means bound to anyone here, but that doesn't make him required to answer any and all questions asked of him.

"True, but the question becomes if you let someone limit your ability to move or if it was truly a matter of not realizing the truth of the matter until it was too late." Is he implying the captain was holding back for the sake of his opponent? Perhaps. He could also be trying to give Han an out so as not to admit that he really didn't think things through during the fight itself.
