  No, it still uses triangles. That seems to be a misunderstanding of how they do their clusters: They switched to a software rasterizer for drawing light volumes and decals into the clustered light buffer, meaning it's now a scatter rather than a gather (parallelized over lights, rather than tiles). This is pretty standard, but it's limited to those low res cluster info buffers, and is only rasterizing a handful of triangles per light.
