Well, different strokes for different folks. People who are interested can see a portion of the video in question here. http://www.aikidojournal.com/media.php?media=video
I believe what you refer to as 'splaying out' is a result of the throw...but then, I've been thrown by Goss Sensei, so that may influence my impression. The style of throwing he uses in his korindo aikido tends to whip you out into a breakfall. His Daito ryu technique can be similar. I'm not rolling gently out of those throws. I don't believe uke is jumping into the throws...the hanbo is actually lifting in a lot of them. 'Course, you could just walk up to Goss Sensei at the Expo this year and take some falls...
Let me know what you think.
