The problem, as described in the video, is that the thumb does not 'snap' to the point touched and then follow the touch as it is dragged. It is therefore difficult at times to actually 'grab' hold of the thumb unless you touch the screen in exactly the right point.
Changing the 'SnapToTicks' property purely makes the movement smoother once it is grabbed.
