I think it's a live ball until INT is called or it goes into DBT, so runners can advance until one of those.
Are we saying that "Batter turns quickly looking down" is active hindrance? I'm having trouble visualizing that, especially if the "turns quickly" is just the head or head and torso w/o the bat shoulder moving toward the ball or catcher.
