I had the exact same thought at the very beginning, until he says this " 2) Be generous - Unless the employee has acted in extreme bad faith or done something terribly wrong, " Which implies that if someone is being "asked to leave" than it's not their fault per say.

I imagine that if it is their fault and they screwed up, "you're fired" is the appropriate thing to say, and generally pretty instantly.
