It will and Calibre will try to use the h1/h2/h3 tags as much as it can to do so.
For Feedbooks, our script is based on Xpath expressions to divide a source HTML into multiple flows (parts, chapters, sections and text flows). They're both quite similar from a user perspective, except that we don't force flows to be 300k long.
