I have been working (I avoid using either "developing" or "maintaining" here on purpose, tough I would have used either of them in another context) on the same code base (mostly) for more than 10 years (doing code, infra and operation) Well, we can nitpick on the wording all we want, but there are times when I feel I'm cleaning my apartment or repairing it (maintenance) and times when I'm extending it (developing). Now if the point of the author (I'm not sure) is that you cannot develop without maintaining because both go hand in hand then I agree.
