“up vote score down vote favorite” appears at the beginning of a questions when the asker carelessly copied a question from Stack Exchange. To reiterate, this appears because it was put there by the asker.
The asker must have realized that within 5 minutes of posting (note that you saw the question when it was less than 5 minutes old). Edits made within 5 minutes of the initial posting are not tracked separately, the edit overwrites the stored initial revision; this is intended as a grace period to fix obvious problems without leaving a permanent record. You also get a grace period after an edit that was recorded. The grace period is reset by some activities such as an edit by another user, or an answer or a comment being posted.
Google indexes the site very quickly, and doesn't necessarily notice grace period edits since they don't update any timestamp, so it may keep the pre-grace-period version in its cache for a while.
