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?

Consider:

What is it Kelley says...endless hours dealing with effects instead of causes?
Check right forearm angle/arc of approach. Make sure the right forearm is being driven (passively by centrifugal force) toward the plane line (not over plane line). Hands correctly driven (actively or passively), correctly down and out produce hinging and the finish swivel. If you are coming over plane, it is certainly possible that your mind will not let you perform correct actions leading up to the finish swivel, because if over plane driving continues, you'll hit the ball dead left.
