I don't think that was the way he portrayed it. He made it seem like they really solved the 2 body problem. Scott Manley even made a comment about how grand that was. I really wish I could find the video to better show what I mean.
I remember Scott Manley asked someone important on the dev team of ksp2 how they approached the 2 body problem. They guy gave a vague answer that they had solved it. If that were true they would have a Nobel Prize but they don't. So then and there I decided that KSP2 will not get my money. Which sucks because I have put a little over 2000 hours into KSP1.
