As Benjamin already pointed out the lower 'rendering' in the image you attached is an artist's impression of what the scene could look like in DX10, that is not actually DX10, read the original source as these other sites only seem to read what they want.
Also what do you mean by 'its instancing' and 'flexibility' and 'improved directx 9 rendering', hardware instancing is possible under DX9 and I'm not sure what the flexibility differences are, other than having the geometry shader. And what do you mean by improved rendering? Other than the speed that geometry can be generated by the geometry shader anything that can be done in DX10 visually can also be emulated in DX9, though in some cases this may be slower.
