Windows SDK always defines it to either 5, or 6 for XP and newer. Nothing in headers depends on it. So it's not the same as with d3dx.
But it is the same as d3dx. Windows headers don't check D3DX_SDK_VERSION and conditionally define things the same way we do. They just ship multiple versions of the same file with different contents and different values of D3DX_SDK_VERSION.
