He is only going back as far as his previous post, but he post he just made changes almost the entire thing, as well as most of my last post. It's almost a complete re-write of his last post, rather than just cutting one part. That's why the line seems blurry to me. He described (I'll just pick a number instead of going to actually count) let's say seven actions, but with his new post only one of them is still applicable, and I didn't actually interrupt him in my post until his third or fourth action.
