David Wilson, in "Bicycle Science" (the bible of bicycle engineering), advocated no knee flex at 6:00, meaning that a rider seeking maximum efficiency should raise his or her saddle just a bit if his or her knee is slightly bent at that position. Any flex there and you lose a significant amount of power from your stroke. That's the theory. In practice, as even Wilson admitted, you need just a wee bit of flex in order to avoid undue stress to the knees, if I recall correctly. In essence, it's possible that the triathlete thought that your knee was bend a bit more than necessary and that your saddle could indeed come up.
