Fine, I guess I understand it now.
The only problem with this is unfortunate reliance on translation interpretations and not a clear visual not from Oda that Hakai broke through Zoro's defense.
Mt actual concern still lies with the fact he's laying down next to all of them after. While I guess now it's an assumption to say Law teleported him, it's also an assumption to say that they all conveniently lined up next to each other after. Like BM and Kaido weren't even concerned that he stood up after that, which indicated to to that he had helped getting out
But OK, I see your point now
