Where can i find this in the code? And what is the reasoning behind this?
Give 250.122(A) [and the articles referenced therein] a quick eyeballing

250.122 (a) doesn't seem very clear to me??

I believe the primary reason one ground can be used for multiple circuits is the assumption you will not have more then one ground fault at the same time.
It's NEC, it's not supposed to be clear
250.122(C) might address your question more specifically.
I believe the primary reasons are that it's highly there will be a ground fault on more than 1 circuit in a multiple circuit system at a time.

No problem at all, glad have your input here.
Kind of spooky we used some of the same words.
Comes from my trying to follow your footsteps so folks may think I'm as intelligent as you...

That's nothing. I've used some of the same words as Albert Einstein.
