That's the point a lot of folks miss... "Rules and precepts" are useful tools, but not the "be-all, end-all" factors in creative expression. There comes a point when you internalize all that stuff and it stews around in your head until you are presented with scenes that benefit from bits and pieces of it, and perhaps from an intuitive exception or two. I don't put too much emphasis on any one structural guideline. It's like being a craftsperson in any field, you have a tool set. Each tool in the set is good for something. You learn how to use it properly. Then maybe a particular scene requires (or "enjoys" combining several ways of thinking you had not yet associated as complementary in some way. Along that path, you break a rule or three, and the result is mesmerizing in surprising ways.

It's like musical composition. Certain musicians have an uncanny knack of combining multiple genres together into a new structural form. It retains elements of the old genres, yet has a characteristic sound and approach all its own. It works precisely because of the blending of styles, and the combining and breaking of multiple rules or… (ahem) precepts. Jazz and progressive rock ensembles have done it time and again.
