In our vampire game, our often Obfuscate using vampire has a habit of seemingly showing up out of nowhere by chiming in on a conversation, which promptly makes everyone think "since when was he there? รต,O". And by this I mean, no one usually notices he's there until he speaks out.
Satoshi pointing Jack out probably won't instantly make everyone realize he's there, but it does make it more likely for them to actually take note of him.
Since, well, Face In The Crowd is a subtle mind trick that affects everyone individually (if he does something that slightly calls to attention, one person could notice and others might not). Unlike Cloak Of Night, which completely erases the vampire's presence.
