Right wrist break(or bending backward)?

[skyou]

I ran into several articles preaching right wrist break intentionally in the start of backswing. It goes the backward bending should be sustained until the impact. I never seen these any players or anyone I played with.
Anyone actually doing this?
I take a look at my right wrist on the top of backswing and found it's bended backward somewhat. Is it normal, or something I'm doing wrong?

It's just another way of saying flat left wrist, and yes your left wrist should be flat at the top, if you have a neutral wrist, and therefore your right wrist should be cupped.

The same holds true at impact. Look at any tour swing and you will see a flat left wrist aty impact, unless it is arched. In either case the right wrist would be bent.
