Another Type of Deception - Legal?

All players establish legal positions, and come set for the required one second. The snapper is on the line, facing the left tackle. He reaches down and in a legal snap motion, hands the ball to the quarterback.

I'm having trouble envisioning this. Could you elaborate? Was the center facing the opponent's goal line with his shoulders parallel to the LOS? Did he not touch the ball until after everyone was set? Please describe the snap.
