I'm still a little confused.

How does this information mesh with leaving the face at practically 90 degrees?

Seems as if they are opposite.

One going down and one going up.

Caught this little ditty on my way out.

Seems simple enough. But, maybe I didn't catch the whole gist. If not, please forgive.

In any event, here's my 'quickie':

In a clinic, Sam Snead called his action in a Lob Shot as "going down and up at the same time".

Clubhead down (to Low Point); Clubface up (Layback through Impact).
