Why is the headstock on the right side for rt. hand players?

Can someone explain to me why this app has a guitar with the headstock and nut facing the wrong way? The point of this app is to help find notes on the fretboard so the headstock should be on the left to resemble what you see when you are looking down as you are playing. Its good that there is a left hand option too, but why screw up the whole orientation?
