Zoro vs Lucci:
- Zoro didn't tie his bandana
- Zoro isn't using three swords
- Zoro hasn't used any named attack (or any attack for that matter)
- Zoro isn't using Haoshoku coating
Zoro is occupied with Lucci, yes, but it doesn't give off the vibes of Zoro's main arc fight.
As for Luffy vs Borsalino, it's yet to be seen if the fight will resume. Luffy punched Borsalino away, and Borsalino never intended to fight Luffy. Now that Saturn has come to kill Vegapunk personally, will Borsalino resume fighting with Luffy? I doubt it.
