Thanks Seanmx,
of course I'm talking full swinging procedure.
My problem is that if I only think of left wrist throwout action the swivel
doesn't happen automatically and I end up with nearly an angled hinge.
On the contrary if I think (as Yoda says) already from the top to wrist roll
thru impact I don't execute any throwout action. Maybe that has something
to do with triggering and release type I'm performing,which I'm not aware of?

Still sounds to me like your getting the concepts of finish swivel and roll a little mixed up. You can swivel regardless which hinge action you use or whether you full roll (horizontal hinge), no roll (angled hinge), or reverse roll (vertical hinge), and it happens well after impact and the hinge action.

For a horizontal hinge, I like to think about my left knuckles and elbow. (Assuming a fairly neutral grip at fix), your knuckles will be pointing towards the ground and your left wrist will be flat until both arms straight. To keep them pointing at the ground as you pivot you'll roll your left arm. Once you can roll no more, the club has to go somewhere (swivel time)...your knuckles won't be pointing at the ground any more as your wrist keeps going and your left arm starts to fold. The elbow? My usual feel is that it stays pointing at the ground even after the left arm starts to fold...seems to help me feel swivel and hinging separately. If you overaccelerate, all this stuff can get out of whack very easily; focusing on pp4 can also help.

Watch Yoda's "Ready to Roll" and hinge action videos again and the video series with Jeff Hull (especially the one where he's doing punch shots). If you practice some punch shots with and without a finish swivel you can better isolate hinging from swivel.
