Page order does not match Visio file when converting to PDF

I have a 2 page Visio diagram that I’m saving to PDF using the Diagram.Save option. Within Visio, I can reorder the pages by moving the page tabs. What I have determined is that regardless of the order of the tabs, the order is always fixed when outputting to PDF. I also noticed that the page IDs are always the same when looping through the Pages collection regardless of the page order within the Visio file. I have also tried changing the page names to see if they are alphabetized, but this also does not appear to be the case. Therefore, I have no idea what determines the order of elements in the Pages collection, which I assume is also what is determining the order in which they appear when saved to PDF.

How can I change this order to match what I have set in Visio? Or at least control it in some other way?

I have attached the sample Visio file and PDF output from Aspose.Diagram showing how the order on output to PDF was impacted.
