Actually, if you look at image #1, Bolt clearly has superior triple extension. Look at the straight line from his heel through his head. Gay has a bit of a break at his hips. He looks like he is trying to stay low.
As far as image #2, it is hard to tell from the angle, but it looks like Bolt is slightly ahead of Gay, even at this stage. Also, note that Bolt’s swing leg very low, but is still further advanced compared to Gay’s. That means that his second step will happen quicker.
Great job on the images!
