Looking at the clothes of people in the scene, a person from further back in the shot seems to be wearing the clothes of the weird looking guy in the OP. That means the assets from a character supposed to be in the background was accidently loaded as a foreground character in Polygon's playthrough. A background character would never have as much detail, and thus he looks weird when brought to the foreground. So, the answer here seem to be the game sometimes loading incorrect assets.
