Yes, those are spare buttons. So if you got an extra fitted to the car in future, lets say parking sensors, you could turn them on or off using on of the spare buttons once programmed.
You can't upgrade the system yourself. Only Volvo or somewhere that specialises in fitting extras like parking sensors etc could do that.
