Not quite… There were only 2 states that could convict without a unanimous jury and New York wasn’t one of them.
What the judge said was that there are 3 different ways you can convict, but the jury doesn’t have to be unanimous on any of the three.
So if 7 jurors decide option 1 makes him guilty, and 3 jurors like option 2 better, and 2 go for option 3, that’s still a unanimous vote for guilty. They just disagree on how they got there.
