The aura around Zoro's hakified swords is literally a waterdowned version of what Roger and WB displayed in the latest chapter. It's unlikely that he doesn't have advanced COA at this point.
Yeah
so what I'm saying is that Roger and WB were shown using barrier CoA on a sword. Zoro, while having strong CoA, does not have that yet.
He did the barrier vs hyozou.
The text under the panel even talks of a magic barrier.

Zoro also has black haki overflowing vs killer and when he holds enma.
I think he was just speaking metaphorically.
if he had barrier, I think Oda would have clearly shown it, like with Roger/WB

We saw the black tendrils on Zoro’s blades in Dressrosa and in Wano.
This chapter proves that Zoro has advanced armement haki in contrary of Oden for example. Especially because in the manga only 3 characters have shown this :
-Roger
-Whitebeard
-Zoro
Two of them are bonafide top tiers, I wonder what it means regarding Zoro’s level
yeah look at the tendrils on Zoro's sword vs the tendrils on Roger's. Its a completely different level.
Hence I say, Zoro isn't advanced yet

Roger literally created a barrier around his sword. Zoro has yet to do anything like that
