Hope you don't mind me jumping in Ditz.
Rows 11 and 12 are locked upright so that they don't impede the exit in case of an evacuation. I understand other airlines and aircraft have the seats unlocked after take off but it is not JQ policy to do so.
So for those who are wanting extra leg room and a seat that also reclines Row 13 is tha place to be on a JQ A320.
