LOL! I can assure I am making nothing up.
There is such a thing as DDR-1 compatability mode in the DDR-II specification and ATi did make use of it. Go check the JEDEC specifications.
Why? probably because their memory controller didn't FULLY support DDR-II until the 9800. Speaking of 9800's with DDR-II on them, there are probably (lots) more 5800 Ultras in existance than these cards.
