The only thing I can see that you might be refering to happens at about 3 minutes into the film.
It's a bouncy landing (not ideal) and the tendency is, on a bounce, to push the nose forwards (again, not ideal - many a nose wheel has taken the full brunt of a landing in this way because the pilot has pushed the nose down too far).
The roll is due to the direction of the wind. To stay on the centreline of the runway the left wing is dipped to allow for the push of the wind from the left.
C'est la.
