In any case: the reason for this behavior is clear.
When you create a Document object, you don't indicate that you want to produce PDF. In the past, you could create a Document object to create RTF, HTML, PDF... It isn't up until you create a PdfWriter that you're actually creating a PDF document. You aren't limited to creating just one PDF document from one Document object. You can create different PdfWriter instances for the same document. For instance: to simultaneously create one PDF that is stored on disk and one PDF that is sent to a browser. (Warning: don't use ColumnText when you do this; don't use direct content either.) You are using page events. Page events are linked to one (and only one) PdfWriter instance. You have access to a Document object in the event's methods. HOWEVER (as documented in the book), this Document object IS NOT the original Document object you created. Instead it's an instance of the PdfDocument class that is created for INTERNAL use. As explained in the book, you should use this PdfDocument object for READ-ONLY purposes. You shouldn't add any content to this object, nor should you change the margins! If you do, you'll experience strange side-effects.
