It's not just that. It's about how close to a human posture they are, as opposed to how close to a four-legged animal they are. Also a heavier torso means leaning forward.
You are right. They might be a civilized race, but they also retain more bestial features. A leaning forward posture sounds more adequate to them, especially the adult males who has a large torso. The cubs could be standing more erect compared to that.
