Why do we have LOS, when we have all these TDRSes?



Just minutes ago, I heard Capcom mention that the ISS was going into an LOS,
and that they would resume their conversation, once they were out of the
LOS.

As far as I can see, there are 10 TDRS satellites distributed fairly evenly,
so that there should be no LOSes.

Why are they still talking about LOSes?
