George, this is part of the problem. Read 406.9 (B)(1) and notice the NEC took time to specify this because it was the intent that on a device all terminals are identified.
Also note the wording not readily removeable
If the NEC intended the same identification for the connection to an outlet box, they would have included wording somewhere to mandate this,
They could also mandate that the boxes would have a not readily removeable green screw installed from the factory, but this is not the case.
Edited to correct a spelling error.
