What you described is the standby process: you're on both flights -- your confirmed flight and the standby flight. It shouldn't have messed up your itinerary at all, if it was done properly; it might have just made it look a little weird.
That said, SDC at a connecting airport should only require inventory on the target flight, so since you said the problem originally was that there was no additional inventory on your first leg, it makes sense that you'd have been able to SDC once you arrived -- which is ultimately what the agent did.
