I disagree. Tori was always going back, never did any irimi, even once! This way he submitted himself to attackers' will, - they decided when and how to attack him. Tori didn't take control of space around him. Normally, against multiple attacks, tori must always go forward and choose next attacker, it will not only impose the correct rhythm, but will assure that simultaneous attack will not be possible.
While at 1st dan it can be OK, for 7th dan it is not acceptable.
