Roughly, yes. I believe that the CA/Browser Forum has extensive documents on what passes for EV (and, notably, you have to be a registered business/organization for EV), and the only rule for OV is that you have to "implement a process" that makes sure you have "verified" the information but doesn't care how stringent you are, so in theory the "extended" part actually means something.
