I think his comment is relevant for people who treat their "private" git history very differently from the "public" git history. My "private" git history contains lots of minor commits for stuff like checkpointing, fixing stupid errors, etc. The commit messages sometimes aren't very informative. I clean things up when I reach a good working state, and the history that becomes public is much simpler, with fewer commits and an informative message on each commit. If I share my crappy "private" history with someone else, then I forfeit my ability to clean it up later. That doesn't matter if you keep a pretty clean history in the first place, but I definitely do not.
