Well, I think that is why you apply full right cyclic with power pedal. If it was just power pedal you'd get mainly yaw. But with power pedal and cyclic you get translation. If the cyclic is full forward, or full right, you get the same horizontal vector. In fully developed VRS, not much. But, add in the full power pedal and you get the sum of the two horizontal vectors, and by pulling full power you lessen the tendency to yaw as you boot in full pedal so the tail rotor is fighting the engine and all that hp is pushing everything to the right.
