Look at this video featuring Brendon DeVore and Mike Malaska.
Mike Malaska is making the same claim that he always propounds and that is the claim that the clubface should be square to the clubhead arc by P6 and that one can then simply swing the clubshaft into impact without having to rotate the left forearm counterclockwise in a supinatory direction in the late downswing in order to square the clubface.
Brendon DeVore seemingly believes that wrongheaded claim.
Here are capture images from that video.
Image 1 shows Brendon at the P4 position. Note that he has a GFLW and that his clubface is roughly parallel to the back of his left hand (GFLW) because he uses a slightly strong-to-neutral left hand grip.
Image 2 shows him at approximately the P5 position. Note that his left hand is descending down the plane with the back of his left hand parallel to his downswing's clubshaft's swingplane. Because the back of his GFLW is parallel to that downswing's swingplane, his clubface must also be parallel to that same plane, and he is not performing any biomechanical movement that will close the clubface relative to the clubhead arc between P4 and P6. To emphasize that golf instructional point, I have drawn a green line parallel to the back of his left hand (GFLW) in image 3 and it is parallel to his clubshaft's swingplane. Note that his clubface is parallel to that red line, and it is not squaring relative to his swingplane.
Here are capture images from a "real life" golf swing video when he was playing golf with John Novosel, where the video frame rate was fast enough to better capture images of his early-mid downswing.
Image 2 is at the P5 position and one can clearly see that the back of his left hand (GFLW) is parallel to his clubshaft's swingplane.
Image 3 is at the P6+ position. Note that the back of his left hand (GFLW) is still parallel to his downswing's swingplane, and note that his clubface is parallel to the back of his left hand, and it is obviously not square to the clubhead arc - because he has not performed any biomechanical action between P4 and P6 to close the clubface. From that P6+ position, he has to get the back of his left hand (GFLW) to face the target by impact in order for his clubface (which is parallel to the back of his left hand) to face the target by impact. The only way that this is biomechanically possible is for Brendon to supinate his left forearm (roll his left forearm in a counterclockwise direction) between P6 and impact (presuming that he does not externally rotate his left humerus to a significant degree between P6 and impact).
How can Brendon and MM be so ignorant regarding golf swing biomechanics that they are not aware of this introvertible fact?
