Is this correct? Doesn't this mean that the end result has different chroma and luma resolutions?

If it says "Image" in the OSD, it refers to scaling both Luma and Chroma at the same time (otherwise it would say Luma)
So what it really does is only 2 steps
1) Double Chroma to 712x480, now matches Luma
2) Double the entire image twice (both Luma and Chroma) to 2848x1920, then downscale both components to 1920x1080
