I am not at all sure what the differences in the versions are. No idea if the issue you described has been corrected. I would hope so though.
there were no comments in the video gallery. After being a part of this forum, I always get a little nervous about other forums, where you don't get as much freedom to talk openly. I fear that things I would want to know about the software are not openly shared.
Also, I cant tell you what scale those models are at. I tend to doubt that they are "real world", like we would be able to in TG. But I also think it would be exceedingly hard to do that animation in TG. The impact of the celestial objects for one. And the camera moves for another. though with the camera path we could do that pretty easy. But navigating all those moving parts in TG would be pretty hard, (or rather getting those moving parts to act the same way). Still, I tend to think that if all that could be done in TG, it would look more real (if realism was the point)... I would guess.
