Unconventional Regulator on Crestar Ceiling Fan

What is this?

Normal fan regulator will have the following :

0 - OFF
1 - Lowest speed
2 - Speed higher than 1
3 - Speed higher than 2
4 - Highest speed

But my Crestar ceiling fan having the following instead :

0 - OFF
1 - Highest speed
2 - Speed lower than 1
3 - Speed lower than 2
4 - Lowest speed

Called up Crestar service center, was given the answer that this is their intended design. What a stupid designer to come out with this!

If any of you Crestar Fan designer see this, please change the design OK!
