There's another quote which explains what they meant by "it's not scripted": it's not using their (text-based) scripting language, but the entire sequence is more or less 100% deterministic, using AI packages to control the behavior:
> The reason it’s AI and not scripting is because it uses goals and rules to determine how something is going to be accomplished.
> In the sense that it’s a sequence of events that happen in a particular order, you might consider it scripted, but the way you set up those events, and how the actors accomplish them, is not scripted.
I was referring to you saying above that the e3 demo was “tightly scripted”. I never suggested it was, just that it was much more complex than what was released.
