Thanks for the pics! Isn't that one a sankyo rather than a shihonage though?
And, I do love that no-hands throw image. Of course, such things would have to be practiced while keeping close in mind the question, "why does uke keep holding on?"
Uke is holding on still because the attack was a choke from behind (Ushiro kubi jime katate dori) and his hand is still caught on the lapel after the escape. This is actually an advanced version of the throw from picture #1.
You would call that one Sankyo - in Yoseikan it's called Yuki Chigai.
