Haven't you ever gone into techniques in randori without thinking about what was to come next, and had your instructor say,"Please use use only Aikido, big circles ..."
Nope. As long as the action was flowing and not "pre-planned", sensei doesn't seem to care. I and others have done techniques in randori that have been absolutely outside of the way our style teaches it. But as long as it was because that's were the technique needed to go and not because we tried to make it look that way it's ok.
