I saw the same thing and had a similar thought. A lot of it comes down to a misunderstanding of the vocabulary. Implicit Atheism =/= Explicit Atheism =/= Agnosticism =/= Apathesim. Admittedly there are a lot of folks who say they are Atheists that are really kinda not Atheists at all b.c. they don't understand the words and never bothered to learn.
