The documentation of `seq-reduce' is probably not perfect, but at least
it tries to explain what reducing means:

    Return the result of calling FUNCTION with INITIAL-VALUE and the
    first element of SEQUENCE, then calling FUNCTION with that result and
    the second element of SEQUENCE, then with that result and the third
    element of SEQUENCE, etc.

    If SEQUENCE is empty, return INITIAL-VALUE and FUNCTION is not called.
