The test they used on DU is completely different. The “test” gives you two pages of words and ask you to check the one you know.
So, as usual, they can make outrageous claims without the need to prove them.

That test does include more difficult words, and it’s possible to receive a higher score (higher vocabulary estimate). As you point out, though, you yourself check the words you know, so if you think you know some but are mistaken (and don’t verify the meaning in a dictionary), your score will be deceptively high.
I missed “avulse”, and got 30325 on the test in this thread. On the one in the other thread, I left these words unchecked — epigone, embonpoint, cantle, oneiromancy, williwaw, funambulist, hypnopompic, opsimath, sparge — and got 41900.
