Simply put there are 2 pkg trees: in the official repos and on your system.
They are supposed to be in-sync -- that's what pacman -Sy does. pacman -S
fetches pkg according to YOUR tree. Over time the sync is lost, so YOUR tree
may have nothing in common with the repo (e.g. some packages may not even
exist anymore).
