Although it is possible to blur (or even screw-up) individual sections of an application (and still have it “work”). Not until those sections are successfully completed, can the control and/or neutralization of the uke be secured.
When correctly applied, (Oyata's) Tuite techniques should not have the ability to be countered. When shown (various) "counters", they inevitably are only available because of a misapplication of the technique. That shouldn't imply that there isn't any that aren't susceptible to being "countered", only that those counters can be avoided with proper technique application.
