Narrative:

Apache (nga X) lands on runway 8. As he is rolling out, I instruct nga Y to taxi into position and hold. I instruct nga X to turn left or right when able and contact ground. He reads back turn left and contact ground. I see the apache turn right and clear the runway. I turn back to the approach end of the runway and clear nga Y for takeoff and put another aircraft in position. As nga Y rotates, he asks why an aircraft is on the runway. I turn to see that the apache has re-entered the runway and is taxiing down to the next intersection.
