Just to make sure there is clarity on what is meant by the clubface position I mention being "closed" at parrallel, here is a great example, where they actually show the stop position at parrallel from both behind and beside. I think the just of the video also supports what I wanted to say, in that the initial proper swing mechanics may determine the fate of swing, or in this case the release. Again, I don't know how many instructional clips I have seen that stress what I quoted from Nicklaus, or what he shows in this video. It is also a good process that can be checked in preshot routine, without cluttering your mind with to much "Swing Thought"
