From what I've read here, I don't think his symptoms fit an appendix close to rupture. First, and probably least indicative is that there are usually at least a few days to a few weeks of intermittent pain before it becomes that acute. Secondly, I haven't heard anyone say he reacted to the pain which would have been severe when the medic pressed down on the area. Most important is that I think there is always fever present when an appendix is close to rupture and I haven't read here that he had a fever. If any of this is incorrect, I'd be happy to learn it from someone with more medical knowledge than I have.
