Does a 10+ visions of death work on PCs?

Hey just a smudge confused about how visions of death works. Just because the don't name PCs mentioned after the 7-9 section. I would say that it always only works in NPCs but I want to make sure that I am interpreting it right . God I love the concept of a Hocus or brainer with this move.

The 'Name NPCs only' bit is actually after both the 7-9 and 10+ results and clearly applies to both, IMO.

we reread this move yesterday night and concluded that it's useable only on NPC
we were right ?

Yes, you were correct.
