No, the system in the video implements field oriented control. This means that when the driver pushes the joystick straight away from them, the robot moves away from the driver, regardless of it's current orientation.
The WPILib Mecanum functions are robot-centric. Pushing away from the driver on the joystick will drive the robot "forward" which may be towards the driver, away from the driver, left-to-right, right-to-left or any direction in between.
EDIT: As we're not using holonomic drive this year, I only took a brief look at the new Mecanum Cartesian VI. Looks like I missed the Gyro Angle input terminal up on top. The system discussed in this thread appears to be a more robust implementation of the same concept.
