What exactly does the condition in the MIT license imply?

To quote the license itself:
Copyright (C) [year] [copyright holders]
Permission is hereby granted, free of charge, to any person obtaining

"Software"), to deal in the Software without restriction, including
without limitation the rights to use, copy, modify, merge, publish,

permit persons to whom the Software is furnished to do so, subject to
the following conditions:
The above copyright notice and this permission notice shall be
included in all copies or substantial portions of the Software.
I am not exactly sure what the bold part implies.
Lets say that I'm creating some library, and I license it under the MIT license. Someone decides to fork that library and to create a closed-source, commercial version. According to the license, he should be free to do that.
However, what does he additionally need to do under those terms? Credit me as the creator? I guess the "above copyright notice" refers to the "Copyright (C) [..." part, but, wouldn't that list me as the author of his code (although I technically typed out the code)?
And wouldn't including the "permission notice" in what is now his library practically license it under the same conditions that I licensed my own library in?
Or, am I interpreting this incorrectly? Does that refer to my obligations to include the copyright and the permission notice?
