The "entire book" setting gives a fixed number of total pages that is unaffected by font/line spacing/margin settings.
Which would suggest it is defaulting back to the ADE synthetic page algorithm. If you are interested, the procedure from Adobe's epub best practices guide is:

Synthetic page names
  1. When page map is not available in the document, Adobe Digital Editions will synthesize a page-map based on the document content. The approach used is the following:
  2. Determine a compressed byte length of each resource which is referenced in the spine, subtracting any known encryption overhead (IV size).
  3. Assume that there is a page for each 1024 bytes in each resource, rounding up to the nearest whole number of pages for each resource.
  4. To map page breaks into a resource, use the number of pages for the resource as determined in step 2, count the number of Unicode characters in the resource; distribute synthetic page breaks in the resource evenly between the characters by dividing the number of characters by the number of pages; if the number of characters don’t divide evenly among the pages, round the number of characters per page up and let the last “page” contain less characters than the rest.
