You would not want a prop going to coarse pitch after a failure, as there is still lots of drag from a coarse prop, and then that drag would increase once you went to feather.
I know SFA about this, but I thought that statement was correct as the purpose of feathering was to get the prop to stop, and that being at course pitch would create more drag than fine because it was windmilling faster on an engine not producing power. Is that not correct?
