I think, you are wrong on it and David correct. Cumulative sum is caused by implicit windowing_clause (default - rows between unbound preceding and current row), which in turn is impossible to define without an order_by_clause in analytic_clause. So, there is clear dependency: order_by_clause implies windowing_clause which causes the cumulative results. Can be looked at http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14223/analysis.htm#sthref1725
