I've used the sarcasm smiley enough to wonder that myself.
The smiley is intended to be touching his nose, which is apparently body language for not telling the truth. There's not a whole lot of options for how to portray sarcasm visually.
I always though of it as a "shhhh" or something. It does kind of look like nose picking too, though.
