No I don't believe that this is by design I believe that it is a result of the smog pump not working when the car is cold, thus not recirculating the uncombusted fuel back for recombustion. The reason it fades off is because as the engine warms a more complete combustion is occuring. Smog pumps are generally only intended to operated at cold engine temperatures.
