The Right Wrist does indeed Flatten during the Finish Swivel as the Right Palm rotates palm-down to the Plane. And most players -- even TOUR players -- tend to Flatten it even sooner (during, not after, the Hinge Action). Accordingly, the Left Wrist for most players -- even TOUR players -- tends to Bend. To the extent these folk play well -- and many do -- it is because they have become expert 'throwers' of the Golf Club.
But ideally, the Left Wrist remains Flat as it only Swivels and then Re-Cocks. When viewed from Down-the-Line, this Re-Cocking of the Flat Left Wrist in its vertical Plane of Motion -- the Left Arm Flying Wedge -- appears somewhat 'cupped' or Bent. [See my recent post on the appearance of the Cocked Left Wrist at the Top.]
But it is not.
It is only Cocked -- as when using a hammer -- in its own vertical plane of motion.
