You are technicaly right in seeing Satellites at all times of the night,but wrong to say you can see Iridium satellites at any time of the night as they are too close to the earths surface and so if the Sun is on the other side of the Earth cannot reflect the suns light as it is blocked by the Earth.
You need a telescope to see the very high Satellites after about 22.00hrs .
These Satellites are from about 10.000kms hight upto 30.000 kms which are usually the Geosynchro Satellites or Spy satellites.
