Yeah that's possible. Maybe it wasn't advanced CoC after all, maybe normal CoC just burst out of Zoro like it bursted out of Luffy when Kaido knocked him out.
I think all feats on the roof top were CoA and it makes sense because Tatsumaki did little damage, Hiryu Kean had Kaido scared, he never landed Shi SHi Son Son or ISDS.
Ashura with CoA makes sense to have scarred Kaido.
Only now we will see CoC Ashura, 9 Swords Coated in CoC, holy fucking shit lol
You also had the entire anti Zoro group jumping to all sorts of conclusions about King's hax about Zoro's ACoC for the first few days since the short summary was an awful representation of the actual chapter XDDD.
