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?
