I'm fairly sure that quote is not factual. Many early appearances of Keanu are clearly a form of video footage; look at the later gameplay scenes to see the actual digital rendering of Keanu, with skin rendering not even matching ten year old games like LA Noire. Even when one Keanu is walking past another in the Morpheus scene, you can see that one is computer generated, with slightly better skin rendering than later, and one is video. Same goes for when Keanu walks through the bullet-time visual effects - the characters involved in the effects are clearly much lower fidelity than the filmed Keanu.
