Great video, by the way. The game concept is impressive (although I'd never want to play it) and the presenter was great.
Essentially, it means that the game's engine is more concerned with the physics of the creature and its surroundings, and creates the animations to match it, instead of having a huge library of animations from which to pick and display.
