It is still claiming two contradictory things.

1) that DNA change is faster than expected.

2) that the amount of DNA change that you might expect from 20,000 years divergence is actually 40,000 years worth of divergence (i.e. the DNA change is slower than expected).

And in neither case is the evolution fast enough to satisfy the needs of Creationists who, although they actually believe in evolution thousands of times faster than evolutionary biology suggest is possible - usually say they don't believe in evolution at all.

I think it's saying that the DNA changes are faster than has been believed because there are more changes than has been believed. But it's hard to be sure with the condensed version.
