The current working directory doesn't need to have a name.  E.g., try the
following:

$ cd /tmp
$ mkdir xxx
$ cd xxx
$ rmdir /tmp/xxx
$ pwd
/tmp/xxx
$ /bin/pwd
pwd: No such file or directory
$ 

pwd knows the path only because it is a special hack in the shell.  The
binary /bin/pwd cannot find out the path to the current directory, because
there is none.
