Have to agree with crab on this one.
For example, you come into land at 9,000' and as you approach your landing spot, you settle due to reaching the limit of your power and settle to the ground. Hence "Settling with power".
Vortex ring state is an aerodynamic phenomenon caused by settling in ones own down wash. It requires a minimum of 300 fpm rate of descent. Therefore, (assuming one has done a good approach), one cannot get when hovering IGE.
