That is not my experience at all. To the contrary, those who write fiction read mostly fiction, and those who write non-fiction read mostly non-fiction.
They're incredibly different skill sets. One is all about argumentation, convincing, facts, and citations. The other is all about imagination, beauty, evocation, flavor.
Obviously they both require assembling nouns and verbs and other parts of speech in sentences, but they seem to be virtually entirely different capabilities at the end of the day.
Writing excellent short stories doesn't really help with crafting effective business communications, design documents, etc. And vice-versa. In fact, I think they can sometimes even be harmful -- the kind of clarity required for non-fiction can constrain imagination in fiction, while the creativity celebrated in fiction can be quite counterproductive when it comes to functional communication -- what is intended to be clever or unique often gets misunderstood.
