"This completes the directory name" does not mean that `pcomplete/cd' performs the completion itself. Indeed it returns something with which the completion is performed. The bug is clearly not there (at step 2), but later (in the fact that `completion-at-point' calls `pcomplete-completions-at-point' three times).
