Yea, super bummed to read it honestly. I think Andrew has always seemed like a stand up guy. We are all human and make mistakes but mistakes are certainly magnified when filmed and viewed a bunch.
I think the unwritten lesson #3 (which I was a bit surprised he didn't discuss) is don't take a shot close to a property boundary if you don't know if you have permission to access. For me that's ~200ish yards with a rifle and probably ~400 with a bow. I've seen well hit animals run pretty far, and even those distances don't guarantee anything but are pretty safe in my experience. He acknowledges his relief that after the shot the animal moved towards public but could have just as easily turned around and ran back on private. Giving the benefit of the doubt he honestly thought it was on public he still knew it was pretty close to private, in which case I would and have passed on the shot. I hunt property boundary areas frequently and always spend time finding land markers that are my "go/no-go" for shot. When I'm unsure I always err on the side of being further on public/property I have access to. Given the description of that quarter section in there I was surprised they were hunting it that close, but maybe that's the only place that the elk were that day IDK, I wasn't there.
