From my investigation of code like this, they are very often lines that are supposed to be at the start of the next chapter. If a conversion of a single file does a split at the headers, then anything that was intended to be at the start of the chapter ends up at the end of the previous chapter file. After a conversion of something like this, I have found the anchor used by the in-line ToC to be at the end of the previous chapter. But this code looks like a separator between the end of one chapter and the start of the next. Or code to push the chapter title down the page.
