I would want them to show that the previous ideas of the involved parties were directly used, rather than someone in the chain coming up with the same idea independently. Does that make sense? Yes, it would be hard to prove.
People can come up with the same "feature" through different paths. For example, having an incoming call announce the person's name associated with the phone number on your answering machine (which you earlier recorded) is the same feature as your cell phone printing the person's name from your contact list when you get a call, but the people making the second one didn't copy the first one's idea, they are totally separate.
