Could someone please explain the Code logic as to why an indoor hot tub needs a 120v GFI receptacle >5' but <10 feet, but an outdoor tub it must be greater than 10 foot.

I realize outdoors there may be more space to allow for the greater distance, but, if it is good inside why would it not be the same outside?

I was also shocked by the vertical clearances required for luminaires near the tubs. I would need to mount lights on the second floor wall to get the clearences if the tub is at the grade of a walk-out basement.
