He is faster on the run because he is fresher off the bike. He might be soft-pedaling for all we know - but at the very least he spent less time on his bike. So if he would have bike a 1:05 40K and bike a 55 then that is 10 minutes less of biking. Less biking equals more energy for running. Go out and ride a tandem sometime, or find one riding and try to hang onto them - it is a big difference regardless of aero position. I have never watched him swim, but it is possible that he is given space by other athletes and isn't climbed over etc, in addition he can draft swimming right off someones chest on their bow wave. There is no sighting involved either - all he has to do is follow the guide, and with a string attached he is going to be following the guide. Regardless of how it all works in actuality, the point I was making is that it is not a simple apples to apples comparison.
