It is only fair since the shuttle puts a "drag" on ISS while attached.

I find it hard to beleive that the shuttle has more drag than the ISS
(unless the docking positions is belly forward).

That's not what Lynndel said. He said it adds drag, not that is has
MORE drag than the station.

And even that was wrong. The station had a ballistic number of 156.80 kg/m^
2 before the shuttle docked, and 163.31 kg/m^2 while it was docked. Lower
ballistic number means more "fluffy" hence more drag, so the shuttle
actually *reduced* the drag deceleration on the station while it was
docked.
