How does it choose a winner in 2 player? Just random?

My 2 kids were playing today and 1 of them was clearly doing better poses as he was actually trying to copy properly, but my other kid was just messing about making whatever shapes he wanted and he kept getting higher points and winning. It got to the point where my kid that was trying his best, just gave up and sat down on the sofa out of the camera view and it took a picture of no-one stood there and for that round he actually got a higher score! Is it just random or is AI or some specific shape matching algorithm used to determine who's pose is the most accurate to the image they're copying?
