Does look unnatural but so is the lighting (see his pupils, two strong lights left and right). I think the weird-looking shadowline comes from his (image left) collar which extends towards the camera and blocks a bit of the left light. The right light meanwhile blows out most of that shadow and only leaves a thin line coming from his neck. Overall makes him look like the hunchback but I think most of that is just optics
I've been looking at this image for way too long now

This can't be true because the skin also has the same light color in the area which is right of the thin shadow and simultaneously behind his neck.
the "right light" (it would be a front light with a slight right orientation) would not wash the shadow out there.
