From what I have heard, the first stage will come in aimed away at the landing, or anything else, and then perform the divert maneuver that they've been testing with Grasshopper/F9R-Dev to put itself over the landing site at the last moment. That way if anything goes wrong before the last few seconds, the rocket won't fall where it was suppose to land. They are definitely planning on doing boost-back to the general area of the launch site though, not aiming for a target down-range. The launch this weekend will have them bringing the stage back closer to land than the previous attempt.
