The four corners are fixed; the diamond motif repeats along each edge. Both this frame and the logo above are drawn into one document-local Form XObject each and invoked for every slice and every page, so the PDF stores the artwork twice rather than twenty-four times - a copy per page would make this file around 40% larger.
The four marks above are four separate <img> elements, not one element repeated - each resolves the same SVG source, so they share one Form XObject between them too.
This page repeats the same fixed vector logo and the same SVG border-image. Nothing about the artwork changes from sheet to sheet, which is exactly the case a per-page copy would pay for twelve times over.
Reuse is keyed on the parsed SVG document and the size it is painted at, so the twelve pages share one form per artwork - and the border-image's own corners and edge tiles, all drawn at the same size, share it too.
