This means that instead of having to route all your sources via some sort of smart switch (AV Amp) that will extract the audio for the selected source, you can feed everything into your TV and the TV will take care of sending whatever audio it's selected out to an external device. It doesn't have to be via HDMI - the TV could do this via a different means (such as Toslink ...) - I had a TV many years ago that had this function via one of it's SCART (remember those ?) sockets.
Keep in mind that ARC is not better than SPDIF ; it's dolby digital 5.1 at best.
