Yes, after the lawn is overseeded post-aeration, most of the seed germinates in the aeration holes. This leaves the soil undisturbed while lush and healthy grass will grow in the holes' place. The point of this is to create extra turf density in areas that really need it, such as a large patch of dead grass where a shed used to be.
