Some of these newer power awnings do not have springs. They will simply continue to roll up in the opposite direction once extended.
For those that do, (have springs) you are right, it would continue to wind the spring but they don't have near the static tension (number of winds closed) the old manual awnings have so I'm thinking the spring might not break. Probably not good for the motor and gears though when it gets that many turns on it.
