There's a reason technical writing has the term 'technical' in it. It should be different from how one would writes for a casual audience (who are reading for fun). When reading as a hobby the mystery of where the story will lead to is part of the fun. But when reading a technical document you don't want there to be a mystery, you want to get the message as soon as possible. So it makes sense to have something upfront that tells the reader what the next couple sentences are about. I wouldn't see it as mediocre writing.
