OK, so if it knew that all vacuumable tuples could be found in 492 pages, and
it scanned only those pages, then how could it be that it reports 16558
removable tuples from those 492 pages, when it has already reported earlier
that it removed 45878 tuples -- a number we know in fact to be correct?  How
could both statements be correct?

It found 45878 dead tuples in 396 pages for the index authors_archive_pkey.

It found 16558 dead tuples in 492 pages for the table authors_archive.
