Yes it does. It disassembles pdf1 by extracting pages 1-3 and disassembles pdf2 by extracting pages 4-5. Then re-assembles the two subsets into a new PDF.
You could extract page1 from pdf1 only and create a pdf, then page2 of pdf1 into a different PDF using something similar to:
<?xml version="1.0" encoding="UTF-8"?>
<DDX xmlns="http://ns.adobe.com/DDX/1.0/">
<PDF result="Final.pdf">
<PDF source="PDF1.pdf" pages="1"/>
</PDF>
<PDF result="Final2.pdf">
<PDF source="PDF1.pdf" pages="2"/>
</PDF>
</DDX>
You can also use the PDFFromBookmarks tag to generate a new document for each level 1 bookmark created in a PDF.
<PDFsFromBookmarks prefix="stmt">
<PDF source="doc1.pdf"/>
</PDFsFromBookmarks>

The Acrobat Javascript can't access the code of a bookmark,so I think we can also use a 3rd party program PDF splitter to split PDF files by pages or bookmark.
