That said, I don't think anyone knows for sure what happened here other than the GA involved....
I always thought that this had to with the voluntary nature of a standby.
If the airline changes your flight they have no requirement to shift your bags to your new flight since the change wasn't something you requested.
If you move yourself (or don't show) the airline removes the bags since you were voluntarily separated from them and that would be cause for suspicion.
