On my 1999 E46, the damn thing always starts up on low fan, even when turned
off and then the car is locked with the same key. I think it was a design
goof which has since been corrected - but possibly not by 2002.
So does my E46 - except if the CC system has been turned completely off,
which can only be done by setting the fan speed to zero with the
increment-decrement (excrement?) buttons. In this case, when the ignition
is next turned on, the CC fan comes on at the lowest speed with all other
settings the same as when shut down. This cannot be changed by
re-programming the key memory.
Does your 5er do this? If not, I guess it only affected the 3 series.
I've not tried, since I always have the fan on. I love the way on a cold
day how it starts very low until the engine warms up then ramps up to heat
the car then finally opens the fresh air vents.
But I'll check today.

As pointed out by others it's because of the key memory.
Here's the list of the options:
