So, if he had his MSP-XXX itinerary and at the last minute a snowstorm made him decide to book BRD-MSP to avoid driving to MSP in the snowstorm and got a VDB to the afternoon flight, do you think the GA would refuse to rebook the MSP-XXX flight to match the new BRD departure? Or the BRD-MSP flight is delayed enough to miss the connection, won't they rebook MSP-XXX even though they are separate tickets? This is like where you have two tickets, one AAA-MSP and a second MSP-XXX and check your bags from AAA to XXX as your final destination. Often the bag check is done spontaneously by the agent without being asked. Despite being two tickets the agents see both and usually act as if they were a single ticket. In this case I can see the GA proactively rebooking everything to line up and if they do that there could be issues restoring the original MSP-XXX flight.
