It appears to me that the attitude is set by three points comprised of the lower rear fuselage and the two engine nacelles. Note that the aircraft has the same attitude once it was stopped. After touching down you can pull on the flight controls all you want, but other forces are in control.

If he had landed on his main landing gear you could watch as the pilot held the nose up until he lost enough airspeed, then the nose falls thru regardless of flight controls. IMO
