Although in some formal sense this statement is always correct, in practical terms we are not at all uncertain
at this point that the analysis is flawed. I have stated exactly why it's wrong. To summarize, it's wrong because:
1) it does not solve the equations of motion, but claims to know what the solution will look like
2) it claims the coriolis force will cause a certain deflection, whereas the coriolis deflection is well known to have a totally different property, the property of maintaining the orbital plane of the Moon in a frame looking in on the solar system from afar
3) the only equation given does not even apply in this situation, as it only works for a single orbit, not an orbit within an orbit as we have here.
Bottom line: I may as well just state that 1+1 = 3, so all the mathbooks must be rewritten, and hold to this position against all arguments to the contrary. The thread I would so generate would be largely the same as this one.
