If they stick up into the airstream they create drag not reduce it

Wrong. They are called vortex generators, they keep airflow attached to the back window and hopefully down to the bootlid, this creates a smaller wake. Smaller wake = less drag.

Haha, just checked out the thraed for the ones there. They will be ineffectual on all the station wagons and vans they are shown on, thats for sure. The ones you need to look at are whats on the roof of the late EVO lancers, they are effective, they will only be effective on something with a bootlid though.
