In "The (Untrue) Story of John Smith and Pocahontas," the author states that "sometimes best history is trumped by a good story." How does the author support this line of reasoning?

The statement from the untrue story of John Smith and Pocahontas that supports the idea that John Smith's account was not reliable is this one. Smith was injured by a gunpowder explosion that force him to return to England for medical care. The English spread the news that reached Pocahontas that Smith is already dead. But at the end, Pocahontas believed that account and hence after, stopped visiting Jamestown.
