That's interesting because the one I saw at my LBS definitely did not have a mount on the seat tube, but still had the 2nd one on the underside of the downtube. Likewise on the Trek web pages you can see that it is not there.
I wonder if it's related to frame size. With a sloping top tube, the seat tube location often has limited clearance for a bottle. On two of my bikes, I can only put a smaller size bottle into the rear mount. I don't recall the size of the bike I saw at my LBS, but maybe in the larger sizes they kept the mount.
