You are correct. However, that is not what the paper is demonstrating. 
It's showing how to find two separate strings that you can tack on the 
end of a arbitrary file (the strings are parameterised by file contents) 
and the resulting MD5 hashes of both new files will be the same. They 
will not be the same as that of the original file.
