Kaido(dragon) couldn't block Zoro's attack, either he tanks it like the other attacks before or he should dodge it. It is like saying kaido(dragon) should tank an ikoku and not dodge it.
The situation of kaido not dodging the others SN's, is because the situation does not permit it. Killer was on top of kaido, law used room, luffy' s attack was to fast, and Kidd attacked an already falling kaido. I don't mean any of the former attack is stronger than that Zoro' s attack.
