The Smooth Height tool does not significantly raise or lower the Terrain height; instead, it averages out nearby areas. This softens the landscape and reduces the appearance of abrupt changes.

For example, smoothing is useful after you paint with brushes containing high frequency patterns. These brush patterns tend to introduce sharp, jagged edges into a landscape, but you can use the Smooth Height tool to soften that roughness.
