So no people didn't write for him.
What he meant by that was obviously, he pulled it off "all by himself" .. he was giving credit for Rock's ability to take that idea and run with it
But look at any Rock backstage promo from this era, or long drawn out promos, especially ones where he is referring to things on the titantron.. The "this is your life" promo is a perfect example of how Russo wrote The Rock's promos.
