You're opening and changing and saving that one file with "elevated
privileges", just as some native Mac OS X application would when it asks you
for the password. (Don't know what happens with the backup copy /a/b/c~ which
GNU Emacs produces. And how the process in reality proceeds; it's easy to
rename the file as the backup copy and open it afterwards in a buffer that has
been renamed, so that you'll be saving saving it as a new file – which makes
handling of date stamps very easy.)
