The body movements and expressions on their faces are equivalent to attenuation in your normal voice and punctuation for lack of a better explanation.
Sign is short hand and difficult to do so these are short cuts of a short, although some do overdo it and those seem to be popular now for some reason(thanks fakebook).
Closed caption may not be available for those events and I've found it to be incomplete alot of times.
I used to watch tv with mute on and just lip read but too many people mumble or have nuances that make hard to do, some are super easy however. That's why we need the sign interpretation. Still it's not a complete transcript, much different than speaking to someone with sign language one on one.

Anyone remember the guy I think it was in FL that was faking it as an interpreter during a hurricane (can't remember exactly why he was on).

It was at Nelson Mandella's memorial service
