Yes, the graft will eventually attach to the bone and new tissue will grow. My medical experience is as a researcher, I'm not a ortho surgeon or any kind of orthopedic doctor, so I don't know all the details. IIRC that's the reason for the tunnel. The bones will attach to the tendon in a couple of ways (Sharpey's fibers and fibrocartilage formation, I think). In general, the blood flow to ACL's is pretty low, which is why they will often graft even when it's only a partial tear. I don't know how or if the blood flow changes for grafts.
But yeah, we're pretty far out of my meager depth at this point.
