Not only is it automatic LOD, it also avoids multiple draw calls for a single pixel. If your geometry is so complex that multiple polygons would render to a single pixel in the end (say, a very complex fractal viewed from far away), Nanite also manages to crunch all these polys into one. Effectively, it makes rendering massive scenes a much more constant amount of draw calls.
