It may be that the producer of the PDF made all the resources shared across all pages - instead of making them page-centric. In that case, when any page is copied (either via XObject or standard page copying) the entire set of resources comes along. That’s how PDF object copying is done.
Sounds like you need a PDF optimizer (or some special software) that will remove unused objects.
