Here's what I think - Ben Hogan swings his hands back on the elbow plane and swings them down on the elbow plane. At the top, to my eye (my ignorant, severely uneducated eye), it seems as if his hands are below the turned shoulder plane. So, by my analysis, Ben Hogan had a "one plane" golf swing. Take that for what it's worth (a grain of something...).
My suggestion would be to educate yourself on what the elbow plane and turned shoulder plane are. A quick forum search will have you swimming in some knowledge. Also, wait and hope for an answer from someone who knows this stuff well, 'cause it ain't me.
