Because you are not distinguishing between flange focal distance, focal length, and bellows draw.

Flange focal distance is the distance from the rear mounting surface of the lens (shutter in these cases) to the film plane, it is shorter than the focal length in the case of most all large format lenses.
The bellows draw is just that - then you add the distance between the front of the lensboard and the optical node of the lens, unless the lens is telephoto or retrofocus (some WA LF lenses are somewhat retro-) and you come up with a number very close the the exact focal length of the lens.
