This is interesting.

I have heard something similar from lovemysan. According to his analysis, the temp sensors are innacurate in Saturns. He found this with the IAT sensor. However, this sensor is identical to the temperature coolant sensor.

I think the SG is reporting what the ECU/PCM *thinks* is the coolant temperature. Therefore, the ECU/PCM thinks that this is the real temprature.

From my POV, it shouldn't matter if the ECU/PCM has been "designed" to work with this type of sensor.

As long as the sensor is working within the original design specs, your car should be ok. If it isn't, however ...
