Check Thunderbird, which is far older than this, and you see almost no "jitter" of this sort. The fact that its on multiple sections of straight track is concerning IMO.
It's not an encouraging sign. I know of very few launch coasters that feature that kind of movement, B&M or otherwise. The wing seating will also make it quite obvious I'm afraid, riding off center of the track, Coasters launching on center of track - maybe not so much of a feeling. One's thighs/legs will feel such movements and interpret that as a change in axial movement, similar to a car going down unsmoothed pavement.
Man I hope its nothing too.
