That page is for the “normal” pardon process, which Saucier wasn’t actually eligible for. What he got was a “political” pardon, which bypasses the whole vetting process described on that page. Whether the political pardons are qualitatively different than normal pardons in terms of their implications is an issue people could argue about, but I’d say most don’t.
