If you drew a line through Tom's right forearm at address extending up through his shoulders I believe you would see his right forearm take away is perfectly on plane at the top. Is not the right forearm take away the single plane swing?

Not necessarily. Plane shifts can occur during the Backstroke and/orthe Downstroke. So, you can go from address to the Top on one plane only (no shift), but you could shift planes during the Downstroke. Or, vice versa. Or, you can shift going up and coming down. Or, you can stay on the same plane throughout. There are a lot of possibilities.
One of the problems in discussing Planes is that there is no Standard. Different instructors have different definitions.
The most common pattern is to start out on what The Golfing Machine defines as the Elbow Plane, shift to the Turn Shoulder Plane going up, and then shift back to the Elbow Plane coming down. As defined in The Golfing Machine, there are not that many Zero Shift golf swings on the PGA tour.
