Good, that's a beginning. This is the way o'sensei wanted ikkyo omote done. It would use the real principle of irimi, or entering. In the old days, you would see nage start this throw, and then, if he didn't have the full advantage on uke, nage woul run uke clear across the dojo, just to turn him over. The idea is to enter a super fast guy's attack, a fast karateka, or a boxer, to uplift him, stretch his loins, twist him over and down.
I'm surprised anyone still uses it in any fashion. Doshu doesn't, Saito's son doesn't. Few use this anymore.
There may be other videos around that show it a little better, but, I haven't been able to find them.
