All satellites reflect sunlight, when not inside the earths shadow. Without the sunlight, we would not be able to see any satellites. Any reflection from sunlight off a satellite at sunset would be extremely small, pin point or star point like, and mostly washed from the light of the sunset.
I would think confusing a satellite with a UFO would be unlikely. In addition, the observer stated the object did not seem to fly in a straight line. Satellites orbit in what appears to be relatively straight lines, and can appear as aircraft to those not familiar with satellites.
I have never observed a satellite making turns or not moving in what appears to be a relatively straight line.
My ping to you has been erased.
