Books and code have different usage patterns.

In books, you typically start from the beginning and read to the end. You consume the book serially and the only breaks you are concerned about are pauses (period, comma, colon, etc.) and page breaks (chapters).

In code, you typically scan. Scanning a book is a painful experience. The sentences never start in the same spot. In code, the heirarchcal structure and text layout helps for scanning and identifying quickly. As someone said previously in this thread, cookbooks are done the same way and for the same reasons.
