PDF is a Paste Up type language.
Each and every item is 'placed' in a designated position on tree page.
While a conversion TO PDF will most likely be linear (top, down). So each item now has PLACE HERE instructions. Calibre conversion does not optomize the code. (it is a LOT of work any way you go.)

A PDF item can be in any order IN THE SOURCE. This is why PDF is a terrible Source.
The creator may place images on the page, then come back and lay down text. then do edits Artifacts are Dropcaps, fleurons and other images any place in the (page under conversion) EPUB
