Sigma lenses are not pretending to be Nikon lenses, but all identify themselves with the proper FL/f numbers

 

Also, in EXIF you will see their names / numbers.

 

The USB-dock is approximately working the same proportion numbers of AFMA (AutoFocus MicroAdjustments). Meaning: It doesn't matter much if you correct the lens only in-camera or use the dock to apply the same correction (and not on camera). It's also possible to correct the lens for all distances and focal lengths (and set in-camera AFMA to 0) and then put it to the next body and just correct the whole system, if necessary.

 

As well as it's possible to do corrections bigger than 20, because both values add. -15 + -12 = -27
