Suggested edits (including tagwiki edits) by users who don't have enough reputation for their changes to show up immediately (2,000 reputation for question/answer edits, 20,000 for tagwiki edits) need two positive reviews to be accepted (with one exception: for a question/answer edit, a positive review by the author of the question/answer is sufficient for the edit to be accepted, even in the total absence of other reviews).
However, this tagwiki edit of mine was accepted with but a single review.
What went wrong?
