Long story short, whole identity system is based on anaglyph technology (look at oldschool 3d movies, red/cyjan), where aesthetics has been devoted to functionality. Main idea is to show two independent messages in one place, one on top of another (it's reflection of studio's mission). With that being said, the easiest way to achieve it is to use different colors for both layers and some filtr that will allow us to watch one layer at time.
Business card seen above is the filtr element, it's made of foil used in 3d glasses. Generally, blue foil eliminates blue color and red foli elimantes red color. If you have 3d glasses like this somewhere, grab them real fast and check it out!
