I agree with Anduin. If a routed unit is routed again, nothing happens. The only time routed units are destroyed is when they are routed prior to a battle, and then would be forced to retreat.It's just like in battle, if you pull routs when all the surviving enemy units are already routed, nothing happens.
Basically, Band of Brigands is just saying that after moving all the neutral units, they will be routed (so that in most cases, you won't be able to use them until next year).
