I'm talking about two different trajectories. Different inclinations,
different semimajor axes, (very) different eccentricities, (very)
different geocentric velocities. There is no plausible mechanism for
ending up with two pieces of the same body in such radically different
orbits- it would require first separating them, and then subjecting each
to a different history of three-body interactions.

If the "foremost" celestial mechanics expert in your country says the
two are similar, he is not competent. I don't notice him speaking out.
