The velocity of the star in the paper, and our star, are both with respect to galactic nucleus. The star is still following orbit, just presumably a very eccentric one. I never said it is not impressive, just that it is similar to typical orbital velocities in our galaxy. The eccentricity of the orbit is the atypical thing here.
