Does pymupdf cut the pdf by the page of file? Or it separate the pdf file by it own rules?

I use pymupdf to handle my pdf file, but I find fitz.open() give me more pages than the file does. So in what kind of situation the program will divide the original page? And I feel confused, if the program do not divide the file by it orignal order of pages, will page.get_pixmap(matrix=mat, alpha=False, clip=clip) work correctly?

example here
FOMC19900207meeting.pdf
This file has 58 pages, but I got 84 from len(fitz.open(input))

I don't understand what you are talking about:

import fitz
doc=fitz.open("FOMC19900207meeting.pdf")
doc.page_count
58
len(doc)
58

The same number is given by every PDF viewer.

Sorry, it's my misstake. I miswrited filename.
