What's the difference/advantage between setting knob limits or motor limits on a wireless follow focus?

What's the difference/advantage between setting knob limits or motor limits on a wireless follow focus? Maybe it's a silly question but I cannot figure out the difference, the WCU4 gives u the option to set motor limits or knob limits.

Limits are for lenses that don't have repeatable focus, like modern still DSLR glass.

 

If you use real cinema glass, you don't really need limits.

 

On remote/wireless follow focus, they automatically calibrate to the lens to find the two furthest points. This way you know where your at when pulling remotely in relationship to the glass.
