It is more specific to say "pathname of the working directory", you are right about that. What I meant was: It is redundant in the sense that the pathname is the identifier of the working directory, and if I ask someone to identify something I will receive in answer an identifier. I.e. If I were to ask a user at their computer "what is the current working directory?" and "what is the pathname of the current working directory?" I will get the same answer.
