Path of War: Expanded

I'm not sure if I'm just confusing it with a discussion I had read about the Bushi but are maneuvers able to be used the same round they are recovered? I know that the Bushi can't use a maneuver the same round they recover it but I can't remember if it was just for the Bushi specifically or if that is going to be the rule for the other recovery methods as well? If it is just for the Bushi then why not also for the harbinger that can recover a maneuver in a similar fashion (albeit with a more costly action)?
