If someone is keeping me hostage so that a third party does something (say, releasing others from jail) - I might be a hostage, but the incident still isn't robbery. You have to steal stuff for it to be robbery. So yes, I'll make the same claim. There is no point in saying that I was a hostage in a robbery if I was in a hostage situation for different reasons.
