I think in english it's called pace, they are not walking properly, they are pacing. Both, Indra and your dog are doing it. It's not very desirable to have a pacing dog in obedience.
What I meant with him not getting the toy is to build frustration and even more interest. If he doesn't get the object of his desire after you built all that frustration they work better.
Maybe somebody else can chime in on that
