I think you're both talking about the same thing. Basically, if you realize you had a typo somewhere in an early commit, or some other random easily fixable error that you simply overlooked and thus isn't part of the evolution of development, you should use rebase -i to squash the fix commit together with the one that introduced the error. It's not about squashing together the entire history of development.
