What does this mean?

Sadly that is all there is. Irish wills all went up in smoke in 1922, so we have to rely on indexes and, in this case, a small abstract.

Yes, I'm well aware of that.

But the indexes and abstracts normally make a distinction between wills and grants of administration.

A close look at Betham's shows that this particular record comes in Series 2: Administrations, vol. 30. This suggests that there was no valid will, only a grant of administration for distributing the estate.
