It's parsing the Cached files. And checking the cached headers. Just b/c
they are on the local disk doesn't mean their not corrupt. So yum has to
check the files and the headers. In caching mode if it finds a corrupt
header it deletes the header(if it can) and removes the file from the
available database.

The downloading and the checking are the same function, more or less.
