I don't think it's really a "leverage" issue at all. It has to do with the way the human body is built and the fact that the leg exerts much more power when only slightly flexed than it does when it's fully flexed. That's why its easier to jump up when the knee is only slightly bent than it is to leap up from a full squat; it's also why designers built eccentric hubs - to take maximum advantage of the greater power afforded by the 5:30-6:30 part of the pedal cycle and to let it coast more in the 11:00-1:00 position where the leg can't perform so much work. In general, the less your knees are bent, the more power you're delivering to the pedals; if you have too much flex at 6:00, then you're not taking advantage of whatyour leg muscles have to offer. Going back to the triathlete's original comment, it's possible he believed our guy could raise his saddle just a bit, take a little more flex out of his stroke, and thereby get a bit more power to the rear wheel.
