    In this case, the Shuttle was leading the ISS.
    The Shuttle, now in a lower orbit, is moving faster.
    
    Notice the current TLEs for the two, found here:
    http://spaceflight.nasa.gov/realdata/elements/index.html
    have the MM for the Shuttle as: 
    15.77928038
    but the MM for the ISS as:
    15.77152653
    
    The higher value means more revs/day, which means faster, which means a few hours after separation you will see STS-122 *leading* the ISS.
