Maybe they just upgraded it, because I think there already exists a facial recognizition software that would recognize faces through different properties of the face (distance between eyes, how wide your mouth is, size of your head...), if I remeber correctly.

Yeah they've had it. The main thing is proper recognition is being implemented, something that hasn't been done yet, at least not in the US. I don't fly enough to be bothered by this, but still pretty easy to bypass.
