I wonder if we can go back to the original topic. The off topic discussions were delightful funny. Since my first post I've learned a lot.
So to summarize, at impact the clubface can be (sometimes)shut but never closed.
Clubface can be open, layback or square depending on the deliberate hinge action one wants to impart.

Is that right?

It would help if you had a Badminton Racket to easily see the Hinge Action through Impact.

1. Horizontal Hinge: Closing Only
   
2. Angled Hinge: Closing with Lay-back
   
3. Vertical Hinge: Lay-back Only

The following is a most excellent video explaining Hinge Action (Rhythm).
