Yes, and that is the point. The same content keeps swapping to a different URL, and because of that some content will be indexed on multiple page URLs and other content will not be indexed at all when you take a snapshot at any particular point in time.
This is a fundamental and damaging flaw in site design, yet one that people shrug off without looking in depth at the consequences. It is quite possible to design a dynamic site where the whole site content does not swap to new URLs every time something else is added.
EDIT: If comments 1 to 5 are always found at the URL "page-1", with the newest content on the highest numbered page URLs, the problem is fixed.
