They may find it unnerving, but I find it some of the worst SA I've ever heard of. I guess if you are in condition white around someone you totally trust, but then, why would you do that to them.
Okay...
You're right. From now on, I will only look at people's hands. When I'm having a conversation with someone, I will stare intently at their hands, as SA is way more important than appearing to be a normal human being who looks at someone's face when they're talking.
Do you ever just chill out and appreciate a joke? It's a subtle psychological trick you can do to mess with someone. There is no need to pick it apart for its situational awareness qualities.
