From min 6:03 until the end of the video: Is that because tori's (blue judogi) left knee is wrapped/entangled around uke's right knee (from the exterior), in a way that there is a risk of getting both knees dislocated when landing? Maybe we could classify this technique as Kinshi-waza (forbidden technique), like Ashi Garami? If uke (white judogi) is strong and confident in his posture, he could still have more leverage to insist with a classic right side Uchi Mata, but the risk of making their wrapped knees explode on the impact with the tatami, remains. So uke (white gi) is in a position to try to escape and avoid being thrown, case in which he could throw himself on his left side and to let go of his grips (like jumping from a car in motion), their legs remain for a moment wrapped in the air, and tori (blue judogi) could risk this, if he doesn't stop his attack: his right foot is trying to keep his balance on the floor, the moment when his right foot could slip backwards and tori's body could fall forward on the back of his neck (higher part of his shoulders), it could collapse like a bag of potatoes, and he could break his own spine, or he will not break his spine but instead his fused cartilages of sixth to tenth right ribs - the false ribs could enter into his abdomen and press with power on his internal organs situated on the front-right side as well (liver, big intestine, gall bladder) - this one happened to me three weeks ago, very painful, as I was tori (the attacker from the exterior). I need two months of light training, to recover. Luckily my opponent didn't hurt himself, he was an experienced black belt, he managed to throw himself on the left, and I apologized to him later when I understood that it was me who has put him at risk in the first place (on top of my own kamikaze risk). In an active fast powerful randori, the knees are so tense in the air when wrapped together (if tori insists on that), it is very different compared to when this technique is been shown in a safe light motion presentation. This is just my personal feedback and experience, and I just came back after a 20 year-long break from judo, I am not an expert, so I imagine more trained judokas who are flexible and supple, maybe could avoid getting themselves injured when doing this. Thank you for the video, it's been very helpful.
