It's not different at all. I've just noticed that on the one hand it *is* possible to use query.order_by(None) to remove any previously set ordering, but on the other hand that _no_select_modifiers() in sqlalchemy/orm/query.py checks for False (and not None). It would be clearer to me if either order_by(False) would work too or - even better - if _no_select_modifiers() would allow None for _order_by.
