ground pin down for always on, ground pin up for switched outlets

I wonder why that would be the criteria for ground pin up vs. down.

It is just done as a way to identify switched outlets. On a "half hot"
the bottom one is switched.

Forget the exact details, 10 years ago, I flipped the receptacle
under the kitchen sink so the disposal and dishwasher worked
correctly. Disposal switched.
