I dont understand this very well. Does it mean that I must move hands first on elbow plane and then rise them, and still maintain shaft on TSP through all this movement?

I start my swing with rfta from address with shaft on elbow plane and hands in impact fix. Then I can feel (from elbow location when I start rising hands) the change of shaft plane (to steeper TSP plane). When I arrive to the top I already have shaft on TSP. That corresponds to single plane shift. I tried rise hands only without changing shaft plane and change shaft plane on the top, but not with success. I tried TSP plane for shaft from address to the top and back to impact, but with this setup I still cannot supply such power as in elbow to TSP shift.

Can I leave (for my full shots) setup with single plane shift with changed shaft plane or focus on zero shift and try build swing and add power after some time ?

Well, whatever your shaft angle at address, start up occurs on that angle. Whatever you do with the Shaft Angle from there until Release is up to you. But, at Release, through Impact and Follow-through, your shaft better stay one one plane.

It's a matter of preference and understanding what you're attempting to do. Like I said, I have no problem starting with my shaft on the Elbow Plane and striking the ball on the TSP (with my hands 2" higher at Impact) with full strokes. It's pretty easy to do, really. But on partial strokes and short strokes, the shaft is on the TSP from the very start.
