Thank you for this interesting question.
I believe that any references to moving information about other books to the p pages would be referring to book lists or short paragraphs (perhaps a paragraph or two).
I could be mistaken, but I do not believe it pertains to anything as large as a 12 page excerpt.
I conferenced with a couple other people and the consensus is to leave the placement at the end of the book as in print.
And, if print and braille page numbering have been used in this transcription, insert un-numbered print page turn indicators.
I hope this helps.
