You are only guessing about implementation. That is not how HLOD works at all. HLOD pregenerate new static meshes under hood and also optionally bake combined materials to textures for simplified materials. Instancing is not useful for at all because each cluster is unique mesh. Because of this there can be additionally optimziations like removing triangles under landscape.

Yup, I’m totally wrong. The training stream is available now and gives a lot more detail on what all of this is and how it works. Implementation details can be found in the engine source code.
