Non-fiction's specific factual assertions and descriptions may or may not be accurate, and can give either a true or a false account of the subject in question. However, authors of such accounts genuinely believe or claim them to be truthful at the time of their composition or, at least, pose them to a convinced audience as historically or empirically factual. Reporting the beliefs of others in a nonfiction format is not necessarily an endorsement of the ultimate veracity of those beliefs, it is simply saying it is true that people believe them (for such topics as mythology).
