I agree that "continuous" is a poor choice of word. Reading the article, it is clear that the author does not care about continuity in the mathematical sense of the term, but rather about allowing the design parameters to vary as a function of the user's environment parameters.
As mentioned in some other comment, a constant function is continuous but is obviously not what the article is about.
