Didn't know that about the translation. But the context stays unchanged.
A guy like Zoro? This guy is seconded in battle intelligence only to luffy, the main character. He has terrifyingly strong affinity to all haki application. The guy that was feared due to his intimidating aura. The guy who beat a logia without touching them (also only seconded by a guy using powerful CoC). Zoro adjusted quickly to it due to his affinity. Just like luffy was able to adjust to using adv CoC mid battle against kaido.
I don't think it's retcon. It's just further power up. Same as kaioken, SS, SS2 and SS3 or fusion for saiyans.
