For the opening movements it describes the first move (hands moving to outside the knees) as a response to having both wrists gripped. You step into a low stance and move the hands apart to pulling them down and apply a headbutt to their face.
The kake uke followed by spearhand is shown as applying a hand throw from having either one or both hands grabbed.
The question raised by someone I was discussing with is why the hands come up through the middle then back down. Ideas?
