Notice the full hip extension during the second pull. His shoulder position results in a backward lean, helping the bar to maintain a "vertical" path. If you feel like you have to reach or step forward to catch the bar, it's probably because you're not achieving full hip extension, among other things. Open up those hips, regardless of the load...it's good for muscle memory and to continually practice full range of motion.
Hips! Hips! Hips!
