Nope. He said it because it is true. Use Dependency Walker
(http://www.dependencywalker.com) to see for yourself what DLLs are linked in.
In fact, *both* DLLs are linked in. Sometimes this works fine, other times it
does not.

If you would like a more visceral demonstration, write a small C++ extension
that uses std::cout.
