Is that not most likely because the student is aligning his head, the middle of the prop and the centre line with each other (or perhaps a less extreme point than the middle of the prop). A lesson I found useful was to taxi the plane straight, with the center line running underneath me, then getting it fixed in my head at what point on the cowling the line appeared at. I then treat that point as the point needed when lining up with the center line when touching down.
