I think they are just seeing if it gives any "ticks" at all, so it won't detect a 2 wire fan even if connected to one if its headers. And as said I'm not even sure it does that, its basicly a mistery bit in the uguru which I think does this :) When I have some more spare time and renewed energy for the uGuru I'll try to connect a 3 wire fan to my other fan headers and see what happens.
