Ok, I downloaded the video to be easier to spot stuff since youtube is a bit limited about what I like to do on videos.
There is no snap, I even checked frame by frame[well there is but not when you think there is].
He does snap,sight, walk, asura, you die.
One of the players is probably lagging[the player recording this lags at second 25] or there is something hidden as packet edit or something that the server has that the basic eathena pack doesn't. I tested even the same range with long mace and yep, that range is stupidly huge.
He looks indeed, based on what I tested offline, that he uses speed pot[or some walk boost or packet edit] because the speed is possible to achive but that range isn't possible normally, at least with my knowledge from how the game works ._.
