In this scenario Zoro does nothing while the battle continues?
If this happens, Zoro probably sits out the fight to cover Luffy, but he's not literally going to be standing around doing nothing while the Yonkou fight. Especially if he doesn't need to protect Luffy.
I also just don't see it happening when Kaido has finally recognised that Zoro is the bearer of Oden's sword and is excited by the battle. I mean the person the two Supernova that were highlighted this chapter were Luffy and Zoro. It would be weird to sidelineo after the special focus he's received so far.
