I agree completely with your interpretation of the phrase. HTML5 is
intended to enhance the web without breaking it, so noting (or even
emphasizing) how it's backwards-compatible is important and useful.

But the phrase should be clarified along similar lines to what you've
articulated. Maybe: "HTML5 can be written in such a way that it is
compatible with all browsers made after X date"?
