They weren't just rendered in real time but also directly from the UE4 editor. I don't like the eurogamer article's title at all since, IMO, nothing was "in-game." The real question is whether or not the tech demo was executed via on-the-fly manipulations or if the whole thing was heavily scripted in advance.

It’s like finding out that the actors on TV are actually tiny people living inside your set. It also helps him show that changes can be made to the game’s design and code, recompiled and executed nearly instantly—a technical feat that has been simply unheard-of in game development. And just like that, the silence in the room becomes reverent. The videogame industry has changed.

Also, the people posting in this thread don't seem to realize that UE4 is intended not so much for them--the gamers--as it is for the developers, or at least that's my understanding from the Wired article. It's all about increasing developer productivity with newer, more streamlined techniques that may have the added benefit of a nicer looking end result. Old techniques will be improved and easier to use, thus enabling devs to make a nicer game in less time than they do now. Some highlights from the Wired article:

In the original Unreal Engine, for example, the ability to render colored lighting led to a rash of games that employed the effect. The same may prove true for UE4′s particle effects, for better or worse. (“Mark my words,” Bleszinski says, “those particles are going to be whored by developers.”)
In one 153-second clip, the Epic team has packed all the show-off effects that have flummoxed developers for years: lens flare, bokeh distortion, lava flow, environmental destruction, fire, and detail in landscapes many miles away. Plus, it’s breathtakingly photo-realistic—or would be if demon knights were, you know, a real thing.
UE4 introduces dynamic lighting, which behaves in response to its own inherent properties rather than a set of preprogrammed effects. In other words, no more faking it. Every light in a scene bounces off every surface, creating accurate reflections. Colors mix, translucent materials glow, and objects viewed through water refract. And it’s all being handled on the fly, as it happens.
And thus was born Kismet 2, which again converts tedious lines of code into an interactive flowchart, complete with pulldown menus that control almost every conceivable aspect of behavior for a given in-game object. Need to determine how many bullets it will take to shatter that reinforced glass? Kismet 2 is your tool. Once behaviors are set, they can be executed immediately and edited on the fly. With Kismet 2, Epic empowers level designers—the people responsible for conceptualizing the world—to breathe life into that world directly, rather than relying on programmers to do it on their behalf. Says Golding, “We’re turning our level designers into godlike creatures who can walk into a world and create with a swipe of their hand.”
