I watched the a few of the clips. Seem like he's a proponent of square to square claming that putting on an arc requires "perefect timing". I actually don't think putting on an arc (open to closed) requires any timing at all. If your ball poisition and mechanics are correct the face will be square at impact.
I've tried putting "square to square" and found it requires manipulation and is not a normal motion - at least not for me.
