I think I know the clip you mean, and I'd say it's rather hard to tell. Certainly, it looks like its an assassination, but without knowing the context of the killing, and the person doing it could well be in the dark brotherhood, but without knowing the context of the killing, it's impossible to say if it's actually a part of a Dark Brotherhood quest, or really any quest, or just the player killing some random person to demonstrate sneak attacks.
