In a real situation you would beat him to the weapon.
John just asked about the etiquette of the sword in this formal presentation in a Dan test for example.
Beating them to the weapon or taking it away is part of more realistic application, perhaps what I'd call the "jutsu" aspect of the art.
In Judo for example the Kata (two person sets) are very regimented and done a precise way, whereas in randori whatever works-works in defeating your opponent. No style points.
You can see it here, precision is stepping, bowing, everything.
I trained at several of these seminars, each one was 4-5 hours and exhausting, mentally (trying to remember it all) and physically.
