Other Middle East and Africa Frequent Flyer Programs - GF : "Is First Flight Bonus" same as "Sign Up On Board Bonus"?

The application for GF FF membership submitted on board mentions 6000 bonus miles for long haul First Class.

Looking over the my activity summary I notice a nice large bonus for first flight, in excess of 6000 miles. Is this bonus one and the same or should I be claiming for a missing sign up bonus?
