There is a HUGE difference between Horizontal Hinging and Finish Swivel...
Separate but intertwined areas...Horizontal hinging is "holding" the Flat Vertical Wrist "vertical to the ground...whereas the Finish Swivel allows the sweetspot plane and the shaft plane to "rotate" to an On-Plane alignment for the finish...
In many cases per grip type...a flat left wrist during the hinge action of impact to follow-through...then after full extension...DOWNWARD,OUTWARD,AND FORWARD...a finish swivel with take place and the left wrist is bent and the right wrist is flattened...
A lot of people confuse the Hinging with the Swivel:
Swingers 3 swivels and horizontal hinging usually:
1.Start-UP Swivel( Standard Wrist Action)
2. Release Swivel
3. Finish swivel
Horizontal hinging takes place between the Release Swivel..Finish swivel...

...When hinge action substitutes for Wrist Action(per7-10) Hinging may feel like one long,slow "swivel" from Top to Finish. On the other hand, the Release Interval may be so Quick as to make even correct Hinge Action to Feel like one instantaneous Swivel.Some players even intentionlly execute Impact as exclusively a Swivel, making Clubface alignments extremely fleeting and erratic.
