How exactly once does either throw depends on relative grip, posture, velocity (that includes direction of movement and "speed", BTW), size of uke and tori, etc.
Here are some simple cues/key points (yoten) that I have used and heard or observed. Nothing is necessarily written in stone.
Sasae Tsurikomi Ashi
1.) Uke lead leg is blocked when it is just passing his other leg, or ahead of his other leg. (Think NNK version of STKA...BTW, what do you think the purpose of that half step on the second step tori makes is?)
2.) Tori hands do a strong tsurikomi action to focus weight on uke lead foot.
3.) Foot of tori support leg points(toes) at 90 degrees across path of uke
1.) Lead leg is blocked when uke legs are even, or blocked leg is behind lead leg. (there is a version though in which the lead leg is blocked when it is well ahead of the other leg.)
2.) Tori hands perform tsurikomi in a manner that lead uke around more horizontally than "up and over". However, that can very considerably.
3.) Foot of tori support leg (toes at 45 degree angle to foward path of uke
My apologies for the verbal descriptions. Some things need to be seen and felt to be appreciated.
Watch some of these, it may help.
From the Kodokan:
The exquisite judo and teaching of Mr. Katanishi:
Well, to be honest, your descriptions make more sense then the clips
Especially in the second clip, I can see hardly any difference between the two, except for the placement of the foot of tori on the leg of uke. This is btw one of the ways many teachers explain them. 'when the foot is somewhere around the knee of uke, it is HG. When it is on the ankle, it is SZKA.' Which is of course nonsense, if that was the only difference.
I am at work atm, so I have no sound. In the last two clips I see some familiar versions with what seems an interesting explanation. I will watch them lateron. Thank you!
