Yes. Because we don't know which files will be updated. So we just get
the 'old' revision of the root, do the update, and then do the diff
between the old root revision and the HEAD.
If we wanted to do the diff between the old revision of the file and
HEAD, we'd have to first crawl the whole working copy, store the
last-committed-rev of each and every file.
