PS4’s DualShock 4 allegedly working with Xbox 360

A new video clip of the PlayStation 4's DualShock 4 controller working with the Xbox 360 has emerged online. YouTuber RageBeefSA posted the video online and claims he managed to get the two to work together "through a combination of JoyToKey, a Cronus Device, and Cronus Bullseye software."

I have my reservations, as the video was filmed with an awkward angle using a "bad" cellphone. Sure, you can see the Xbox 360 reacting to the button command inputs on the DualShock 4, but how can we be sure that someone isn't actually controller the Xbox 360 with an actual controller off-screen?

Maybe I'm just being a conspiracy nut. The DualShock 4 has already been seen working on PC and Mac, and a previous video showed limited functionality with the PS3. Still, given that Xbox 360 is the rival console to Sony, it's a bit odd.
