You clearly can't interpretate. Zoro was holding back this whole time but Asura's on Kaido because of Enma sucking his haki.
And you are right Zoro has ACoC when he stop holding back and unleashes all he have. But he did that already on Asura against Kaido. The only attack is making scar on Kaido is the one from Oden which he is using ACoC.

Zoro was only holding back because he was scared that it would kill him to release the haki Enma wanted him to once he embraced it and gave Enma the haki it wanted we started to see CoC.
Hence the reason why I say without Enma Zoro isn't put in the situation where his output of haki is at a level it forces his dormant CoC to come out.
