They should have just been able to go back up the ramp from the downstairs waiting area to the load area, and let the CM know they were doing a rider swanp.
Not true, and your situation proves that. If yuou had the GAC card with you and presented it to the CM out front (at either the Stand-by *or* the FastPass Return entrance), they should have given you a "switch pass".
But, like JMTStone says, you are permitted to use the FastPasses themselves as your own "rider switch passes". If you have four in your group, and one doesn't want to ride (or, is unable to), get all four FastPasses anyways, and let someone ride twice.
