    Well I'm going to use a Judo example with Mifune.

    [ame="https://www.youtube.com/watch?v=UKjasin7Fp8"]Kyuzo Mifune - 089 - Ashi Waza - O Soto Gari - YouTube[/ame]

    Instead of the leg going straight back and ending up behind, the leg does a kind of curve and mifune ends up with both feet on the ground.

    The techniques in your clips are

    1. 切(Qie) - Front cut,
    2. 撩(Liao) - Back kick,

    that you use your right leg to attack the outside of your opponent's right leg (the 4th side).

    The twist and spring is to use your right leg to attack the inside of your opponent's left leg (the 2nd side).

    Opps. How about this one:

    [ame="https://www.youtube.com/watch?v=vZz17C5AiBM"]Kyuzo Mifune - 098 - Ashi Waza - Uchi Mata - YouTube[/ame]

    I'm not seeing really any twist of the spine in any of the videos you posted or with Mifune's video. So alignment is right. However, was excessive force used? Excessive force could be a sign of unneeded tension.

    I think it can be called integrated force. training connection, cross body has the effect of uniting.. Also in the case of opposing directions the dantien goes one way on the bottom half and another on the top half for example.
    . Rotating balls do exactly that. So whilst it's not a real ball with real rotation - the feeling or training of it with that visualisation has the desired effect in and around the desired area.

    The lower abdomen/"core" splits force in 2 basic directions. Any ball rotating in any plane - if you place your hands anywhere but on either side of any plane of axis, your hands will be moved in opposing directions.

    In the technique you bring up the bottom half of the dantien/ core takes the leg one way and at the same time the upper half of the dantien/ core takes the upper torso the other way. So the same principle is in my push and pull example it's just that it's all happening in the upper body.

    The dantien can be thought of like a nexus where body connection is concerned.

    That technique in your clip is "挑(Tiao) - leg lift" that you use your right leg to attack and lift the inside of your opponent's left leg (the 2nd side).

    The

    - 弹 (Tan) - spring (2nd side), a horizontal force vector.
    - 挑(Tiao) - leg lift (2nd side), a vertical force vector.
    - 切(Qie) - front cut (4th side), a 45 degree upward force vector.
    - 撩(Liao) - back kick (4th side), a 45 degree upward force vector.

    are all "leg skill" used in wrestling.

    The "twist and spring" is to use your arm to twist your opponent's body and spring his leg "outward" at the same time. You twist your arms but you don't need to twist your own spine. You start from facing to your opponent. You still end with facing to your opponent (this is why you don't need to twist your own spine).

    Here is another clip for "twist and spring". This technique is commonly used in Chinese wrestling. I have not seen it in any Judo clip yet.

    Interesting. Very well thought out example YKW.

    IMHO, the technique is using leaning power more than full body principle for power. Nothing wrong with it, just more emphasis on a different power generation method.

    It is used in Judo too. I believe the following uki waza would be similar from Judo, only it is a sacrifice throw:
