In the current development sources, this fragment was changed to say:

    (VARIABLE . STARTPOS)
         Use VARIABLE (a symbol) as the history list, and assume that the
         initial history position is STARTPOS (a nonnegative integer).

         Specifying 0 for STARTPOS is equivalent to just specifying the
         symbol VARIABLE.  `previous-history-element' will display the most
         recent element of the history list in the minibuffer.  If you
         specify a positive STARTPOS, the minibuffer history functions
         behave as if `(elt VARIABLE (1- STARTPOS))' were the history
         element currently shown in the minibuffer.

Does the above answers your question?
