From my inspection, you can have bottom pull (which is how I have it set up) or you can have top pull. Just rout the cable through the appropriate path on the arms.

The difference is the length of the arm which goes from the clam to the cage. I ride a Specialized epic and the seat tube has a welded feature on it just above where I had the deraillure clamped. I mistakenly bought a the long arm XT deraillure and I can't move it up far enough because of the welds, so had to get this one (which is the equivalent of the Deore one that was on it previously). If there's nothing on your seat tube (no bolts or welds) you could probably use either.

It should work, maybe even better since the extremes in the cassete are closer and there will not be even a minimal rubbing of chain in the front der.
