SSE was made after 3DNow, while SSE4a was made after Intel published its SSE4 extensions. The instructions provided by SSE and 3DNow do not intersect.
I feel like these points on SSE4a not being a SSE4 derivative are derived from the following rather than any actual technical reason:

If you're going to claim it's a derivative, that # should be AT LEAST 50%, if not higher. IMHO
And this has nothing to do with me liking Intel - I actually root for AMD which is why SSE4a is so disappointing.
