I think I remember you said that in swinging the left wrist is fully uncocked just after low point. Is that right ?

With Horizontal hinging the wrist will be most uncocked fractionally (and I mean really really really really fractionally) just past low point.

What happens after full lever extension ? Does the left wrist recoil back to cocked ?

Through the impact interval with Horizontal Hinging your left wrist will recock to some degree... whereas the angled hinging will become more and more uncocked as the left arm gets closer to the plane. Now assuming you do a flat 'flat' left wrist finish swivel - the degrees of wristcock and wristroll become simultaneous and the wrist will cock 90 degrees when the hand is rolled to the plane. Now if you did a flat to the plane regardless of wherever the left arm may be in relation to the plane...well now they become as sequenced as you like bearing in mind where your hinge action is in relation to followthrough and what you were doing there previously.....
