What you are referring to is the onboard variable-based tracking of devices offered by Logitech remotes. No feedback is being provided to the remote in this case. The remote is internally keeping track of a given components power or input status for instance based on the last power or input IR code sent by the remote. For components which do not offer discrete power or input IR codes this variable tracking allows for more intelligent macros to be sent from the remote when changing from one activity to another. Of course the remote is acting under the presumption that any given IR code sent from the remote is successfully being received by the given component. The remote is also relying on the fact that no one is changing the state of a given device physically or with another remote.
