If you are assuming that it isn't overheating SIMPLY because it is going back down (and an overheating car would stay hot) then you could be wrong.
If the fans were to NOT be coming on, for instance, your car would raise to the upper range, then the HIGH fan would come on, cooling the system lower... fans would kick off, and you would repeat the process..
My point is only that the car is not PROVEN not to be overheating simply because the guage is going down, again.
