Yup, that's how it's supposed to work. It modifies the hidden edge display - if hidden edges are not being displayed at all then there is nothing to modify.

So "Display hidden lines" controls whether hidden lines are being displayed at all. When they are being displayed, there are 2 different ways they can be displayed - on everything (same as before) or only on selected objects, controlled by the "Hidden edges on selected only" option.
