If the reservoir is overfilled and the oil gets very hot, the oil gets blown out of the overflow and - well you can see the result.
You will see the dipstick has HOT & COLD markings, I always look at mine cold , not that it makes any difference.... Just make sure the oil in the reservoir is @ the correct level, too low and you risk a damaged PS pump.
