Its basicly the same system, minus one little thing. One way or another, its not an "exciting" feature or "innovative".
As for corpserunning, you dont have to. You can spawn at the graveyard and just click your "lets-go-back-to-town" button. Its merely a step up from WoWs system. Instead of taking time to travel from 1 waypoint to another, its instant. And you arent restricted to 1 location to teleport to, or a cooldown. Sure, its great to have an easier and faster time traveling around. But again, its not exactly innovative.
And thats just what my point was, the guy who made that video made things that arent anything all that special (except the overflow server) seem like its amazingly revolutionairy. Its not. Keep your head on your shoulders people.
