I was just messing around with the settings on my Sprint lg g2. You can also turn off the screen by double tapping on an empty area. I've got some empty space on a couple of my home screens with no apps or widgets, double tapping will turn off the screen.

Haven't you heard of knock-on and knock-off features? Were you thinking you can only turn the screen on by double tapping it?
