I never said that both wrists hinge

I was explaining what happens when the left wrist hinges the right wrist is a by product.

Just to make this clear to you setup while looking at a mirror so you are able to see you're backswing, now take it to the top what do you see?

I will tell you with certainty what you see
You're left wrist is flat and your right wrist is bent, this should be maintained all the way down to impact.

I will leave you with one final thought

there are numerous ways to explain the golf swing

apparently you were confused with the manner in which I explained it
