From my perspective, it basically boils down to me thinking, "Ambrus is often picky about his PC's actions. Because of that, I'm feeling some trepidation about how far beyond his stated declaration I should take his character. Should I go ahead and have the goblin fire, even though it may mean I get bombarded with complaints if I do? Or should I go with what Ambrus wrote, sticking only to what he officially declared? Hmmm...I don't like being yelled at, so I'll stick to what he wrote because, after all, he's an adult, can write well, may still be in Hide/Move Silently mode, and probably would've indicated if he wanted to do otherwise."
As it turned out, I received a complaint anyway. Which I have now rectified. I'm not feeling upset about it, but I do consider it a done deal seeing as how combat's over.
