Buffering typically just consumes the same live stream until there's enough in the buffer. No difference other than the request rate being potentially higher. At least I can confidently say that for the standard players/video platforms. NetFlix could be doing something different. I'm not sure if they have their own protocols. But I'd be very surprised if the buffering used a completely different mechanism.
