Can you open the trunk with the Saris Bones 2 trunk rack attached? I'm looking into purchasing a Saris Bones 2 bike rack for daily use (driving part way, then biking the rest of the way to avoid parking fees), and occasional use on long road trips. I intend to keep it on the car most of the time. This is a trunk-mounted rack that bears its load on the rear bumper on two rubber feet.

My question is, can the trunk be opened if the rack is still attached to the car? Obviously without a bike mounted on it (but if it works with a bike mounted too, bonus). Will the feet slide off the bottom of the trunk when it is lifted, or is there enough grip for it to stay?

Details: I have a 1999 Volkswagen Jetta. Because the trunk is held open by hydraulic shocks and not the balanced hinges of most American cars, the trunk does not swing freely and must be pulled open and closed manually. Shutting it requires a bit of force (maybe ten pounds), so it can bear a bit of weight without slamming shut.

Apparently the Saris Bones is a pretty well-known and popular rack, so I'm hoping somebody can give me their experiences with it. I've been searching online and can't find a straight answer.
I have a different Saris rack that has one top foot and two lower feet like the one you show, but I didn't find it on their website now.  It has six straps, two top, two side, and two bottom.  I use it on the hatch of a Lexus CT200h, same as Prius C.  The lower feet sit on the bumper for me, not on the hatch.  I can open the hatch when no bikes are installed with no problem.  In fact, I open the hatch to install the rack because the side and bottom clips are hard to get on with the hatch closed.  I had a previous Thule rack with the same experience except that you have to keep your head out of the way when closing the hatch.  All the feet of that one sat on the hatch.
