Haha, absolutely, it's a terrible example with terrible design that I pulled out of thin air, but it was just to illustrate the point of how even seemingly innocuous changes can have major consequences.
That's the whole point of continuous integration, and that's what the author is trying to push. That you actually move faster by letting people push and fix bugs versus push a change, wait some time for a code review (somewhere 1min...1day), go back and forth on some style things, maybe a the reviewer managed to win the game of "spot the bug," and then ship, and then fix any delinquent bugs.
Like, unless if that middle reviewer is doing something that really can't be done elsewhere, it just serves to slow things down.
