Right, and since the string excursion is elliptical, a lower 
pitch comes from the horizontal motion (from the flagpoling 
pin), than comes from the vertical motion. Result - false 
beat. Seating the string jams it into the notch edge enough, 
sometimes, to stop the flagpoling, which temporarily clears up 
the false beat.
