He could actually just lose two of the loops there. he has what I call a four sided tri, where three loops on the base of the poly converge at the top to form the point of the tri shape leaving one loop on its own. It would be better to join the top point/edge to meet the middle point of the 3 at the base then delet the remaining loops and edit accordingly. have a look at my diagram, as crude as it is it should make sense
