The more important information is that since Zoro is using a new attack, most probably a CoC coated one, he is cutting King down in his most durable form - with his flames active - and not after cheaply cutting his flames off.
Since that is how Zoro's fights are usually written - needed BoAT to cut through steel vs Mr.1, needed Ashura to cut through Kaku in EL and he probably is going to use ACoC to cut through and overwhelm King's Lunarian hax.
It is just speculation though at this point, since we have no information about the combat part of the chapter except for two named attacks XD.
