Everybody learns differently. The most glaring example to me, in demonstrating proven, highly-skilled freehand sharpening, is set by Jason B. on the forum. I periodically go back and watch his videos on YouTube to study what his hands are doing with blade & stone. So far as I know, he always holds the handle in his left hand and flips the blade between edge-away and spine-away in doing both sides of the knife. He seems to have done pretty well with that.
I've progressed a lot since learning to switch hands in pursuit of something emulating ambidexterity. But that hasn't stopped me from occasionally changing things up and flipping the blade over in the same hand, ala Jason B. style. And I'm getting better with that too, in discovering that the 'feel' for flush bevel contact, acquired in all my practice with both hands, is still helping me when I try it a different way. So, I'm convinced that if or when somebody really commits to teaching their hands to do it, the hands will learn, no matter which technique or style it may be.
