Every other selection asks a question about each face on its own: is it pointing up, is it above this line. This one asks what touches what you already picked.
That is how a rule about neighbours gets written: a cell next to a built one, a border one ring out from a region, a halo around a crater. It needs the geometry itself, because a field alone cannot know what neighbours what.
