He's not working his legs though, he's most probably targeting working his gluts. ITB is often a butt issue. It's not what is best, it's what targets what.
I'd go back. But it depends where your issue is.
I'd also do clam shells and two legged squats, plus power band work, side steps, really work the glut medius. In runners it's notoriously under fired for such an important stability muscle.
However also walk through the running motion, when fit you should feel in control, with poor stability, often associated with ITB issues you will wobble through the steps.
