     Tom,
          I have seen this effect several times before. In
     fact, if you can believe it, I sometimes look forward
     to slight cirrus overcast when a bright Iridium is
     coming up to see this effect. And yes, the action
     seems to have the sweep in the opposite direction to
     the satellite motion.
