Short video of a young pilot on his first glider solo flight

Actually, my point was not so much about using both hands to hold the stick, which at times (and in young age) may be necessary to add the strength and stability, but about the sequence. In the footage at 1:18 I see the left hand underneath, with the right wrapped around it. I would feel safer with the right hand holding the control stick, and the left supporting it, but ready at any fraction of a second to move to do its proper tasks like the release or brakes. I hope I'm not being picky...
