Yes, but as the OP describes, the process involved much iteration and constant feedback and energy from Jobs, not just a memo of what he wanted to see on launch day
I think the point was that Jobs was working with the teams as a contributor more than a dictator. It very specifically pointed out that Jobs' ideas were decoupled from his role as CEO (as were everyone else's) so there were just lots of ideas, and the best ones stayed around while the rest were thrown out.
Perhaps Jobs started that process, but I'm sure it still exists with him gone.
If Jobs was Apple, there should still be some skunkworks projects left behind to ship and the numbers are still favorable to Apple.
