It seems the author was trying to apply KISS to web sites here, but being unnecessarily dogmatic they added additional complexity over mundate aspects such as whether you call your CSS /dist/output.css or /styles.css. This is completely irrelevant. HTML is a presentation layer, as such it's 99% the output of some other layer. HTML first therefore is the wrong mindset. You can't have an HTML first CMS for example, that's a recipe for spaghetti disaster. You need to define clear, constrained models that then you can adapt for given media. I feel almost weird arguing with this site, because in general I also prefer simple HTML where possible, and I can't stand overdesigned JS-generated framework monsters. But going from one extreme to another is not smart. No simple rule is a substitute for "intelligence first", and intelligence has lots of subtle rules and relies on rich context to make the right decisions for that context. Nice domain name though.
