I think they just playtest with people that have no games experience to see what they think.
I doubt they'd remove features like the headcrab moving the bucket, they laugh at their playtesters too, but they probably use their input as perspective on things they might take for granted as developers.
I'm kind of glad Boneworks turned out the way it was, because I'm more inclined to believe Valve's approach might be the better one, especially if they let you customize the game a bit to meet your expectations as a seasoned VR user.
