Can't really remember him saying that but then again I can't really remember all the specific details of the video so will have to watch it again. If u know the part of it, I can confirm.
What I do kno tho is that Yuderon's stance on Zoro's CoC seems to be that given Enma is a sword that draws out Haki, Enma drew out Zoro's CoC from his subconscious hence why he himself doesn't believe that he has it.
