And why would Yamato follow such an order from Luffy? Yamato isn't fighting Kaido for Luffy? She doesn't even believe that Luffy can defeat Kaido:
It would also be kind of tasteless for Luffy to interrupt her personal fight and tell her to deal with Jack.
Like King vs Zoro, there's no story reason for Yamato vs Jack.
Unlike King vs Zoro, doesn't Yamato actually need to see her Father be defeated?
It's more important for Yamato to witness Luffy vs Kaido and come to trust him to defeat her Father than for her to fuck off to fight Jack.
Yamato needs a moment like this:
Yamato vs Jack wouldn't just be pointless for the story, it might be bad writing. Yamato actually needs to witness Kaido's downfall.
