On checking the review queue for low quality posts this answer appeared in the queue. It didn't seem to be low quality by the usual standards (I.e. its not to short or with particularly bad content. I checked the edit history and there a weird (presumably accidental) revision that was subsequently rolled back.
I can only assume this first edit triggered the low quality criteria despite being rolled back before I even checked the review queue. Was this the situation, and if so is this intentional? It makes answers that are not particularly bad be mistaken for poor answers and judged accordingly.
