To see unexpected satellites is not that surprising if you know that at any
moment there are a few hundred satellites above you and there is only one of
them for which you have made a prediction.
It becomes more difficult when you have made a prediction for one satellite
and another is following the same track at approximately the same angular
speed.  If both objects are of the same brightness and no flash behaviour is
visible then it is difficult to distinguish them directly.  An
identification has to be made afterwards.
