You are right, but no, there are better words to say that Kaidou dodged the attack, in that dialogue Zoro means that he missed BUT the reason he missed was because Kaidou avoided the attack.
I've been in this forum for a few months so I guess people are going to argue saying things like Zoro missed because with 1 eye can't measure the distance or something like that so let me say, as someone said here already, he didn't miss because he wanted, he missed because Kaidou moved.
