Zoro wanted the opponent to be on his knee or back, for a term of defeated. Thus, he wanted to finish his fight BUT Jimbei didn't want to wait. He told Zoro that the fight was already the same as finished. Then Jimbei softly pushed Lucci to be on his knee to persuade Zoro, kinda like "look Zoro, he is done, what are you trying to do, huh? Let's go"
