ESA's orbit is itself constantly changing. Orbits are not fixed. They move constantly from orbital perturbation from Earth's gravity field, the moon's gravity field and, notably at these low altitudes, atmospheric drag. Again, who moved into who's path is not something you're going to determine. Yes SpaceX was lowering its orbit, but it's crossing hundreds of satellites paths by doing that, and even the orbit SpaceX satellites are in are shared by many other satellites. LEO is crowded.
