One chapter after Zoro was in "KoH state", we see him use two swords... which was how he faced Lucci all the way until the finisher, where he pulls the third sword from the scabbard and catches the one in the air.
The fight being offscreened, doesnt mean you jump to random conclusions about Zoro using things that he never used. Lucci never faced KoH, y'all just claimed he did cuz Oda drew that one panel where they both exchanged dialogue.
