I have the exact same thing... I noticed it right after I picked up the car (May 2003) and thought it was weird. About a year later, when my sunroof cassette was being replaced, I pointed that out to the technician while the whole roof was disassembled and the switch was just dangling from the roof. Of course I asked him to just "reverse" it and put it back. He said he could not do anything, since it required chaning something in the circuitry... I was in a hurry and did not want to insist; so, it is still backwards.
I guess another "quirk" of MINI ownership
