Yes INDEED. Sometime during their moulting stage, they can roll-down but later can still be able to manage the roll more efficiently. If that 07 have been flown ever since 07 and still roll down then it's most likely a roll down. Also, the feeding also effect their rolling habits, so feed your birds what they suppose to be eating when you are ready to fly them.
