I can see whey it's confusing. I was confused myself, but I now have clarification to share.
The repeated material (i.e., cast of characters, pronunciation key, etc.) is placed at the end of the front matter in all appropriate volumes. The PRINT PAGE NUMBERS of these items are listed in print order on the title page. If there is more than one repeated item, like both cast of characters and pronunciation, these would be placed at the end of the front matter in the print page order that applies just to them, but both are at the end of the front matter. All the print page numbers on the title page are listed in print page order.
Hope that helps.
