As you undo them (lefty loosey) they rise out of the clip. I found on a couple of mine I had to hold the edge to stop the whole thing rotating. It's like the old push pin types but a lot easier to work with. Not the best photo, but should be able to see how they work. 
This isn't a vertical position to unlatch type retainer. The screw goes down the middle and expands it so it can't pull out.
