Nice variation! I guess he set-up is illegal in competition, because he's using two hands to free the arm? Still a cool variation I'd like to practice. Thanks.

There is nothing wrong with it, but you have to attack 'immediately', where IJFs intepretation of what is immediate is anything between 1 second to 5 seconds, depending on what you do with it. All you have to do tap the inside leg to unbalance him with ko-uchi-gari and you've 'done something' with it.

No. SPFransen is correct.

ARTICLE 25 - Prohibited Acts and Penalties, SHIDO (Slight Infringements Group),
(a) 23. Breaking the grip of the opponent with 2 hands.

This a stupid rule that forces judoka to do things in a technically inefficient manner. It was made necessary because their other stupid rule about not attacking the legs which led ... predictably ... to an increase in the intensity and importance of grip fighting.

This form of kata guruma would be quite useful to overcome the imposed limitations of judo due to the leg rule, but you won't be able to break uke's grip with both hands as shown to set it it up, so you'll need to intercept uke's hand before he grabs your eri.

There's the rules and there's the adopted intepretations of the rules. The only way to grip-break using two hands now is if its part of a technique, e.g. two-on-one hand tai-otoshi, seoi-nage, and so on. You can break the grip with two hands if it is immediately followed up by a technique or legitimate attempt to do so in a continuous motion.

I have to admit that I wasn't aware of that interpretation.  This is really what's maddening about the IJF.  They change their minds so often you can't keep on top of it unless you go to every single referee clinic.
Well, good to know anyway. Honestly though, I don't see the point of having any restrictions on gripping.  In theory it's supposed to prevent stalling but in practice all it seems to do is limit the variety of possible attacks by making attacks from a "non standard" grip more challanging to set up and execute.
