Because it did. I'm sure they made tests and decided it worked good enough. It wasn't made only for faces/persons especially not for images with 2 faced far apart. It also never was meant to decide between 2 possibly "image centers". Its not biased because you can craft an image where it procedure unwanted results. The only persons biased are the people who see a bias in everything.
