I took the anecdote to be about why these people would be let go even outside of layoffs. Layoffs, I'm willing to say, can and should be somewhat random. At best, they are controlled burns of a forest that you can't see. It will destabilize the ones that remain and you don't know how many of them you will now lose.
To the rest, certainly possible. My sports metaphor certainly implies a pipeline of workers that will replace each other in a somewhat predictable order. But that feels like a different thing than "they may be producing great code, but are not reinventing the world."
