That is patently false.

Assume N+1 UPS, with each UPS module having its own ATS fed from a utility and emergency bus. Then you can even individually maintain each UPS module and ATS. Bonus and score.

And if it's a really good place, you have two of the above (2(n+1)) and each of your power cords goes to one each.
