No Zoro said King never said he is a swordsman, we don't know if Zoro considers King a swordsman
King: I dont have time for battle form and styles
Cabiji also told Zoro he is not a swordsman but Zoro still considered him a swordsman, its a call back
Zoro referred to Cabiji using non sword fighting techniques as tricks
Cabiji also said it was tricks
Did you forget the part, where Cabiji said he'll use his "Real Swordsmanship" And Didn't use not tricks
+ Whos to say you cant have multiple fighting style Caibji could be a swordsman and also acrobatics
