Well, if you interpret "neighborhood" in this context as referring to phase space or to classes or orbits, you could maybe plausibly interpret it as allowing Neptune but not Pluto. There are a lot of "plutinos" in Pluto-like orbits (that are resonant with Neptune in the same way as Pluto) but anything in a Neptune-like orbit is orbiting Neptune.
...unless it's something like a Neptune Trojan (do any such things exist?) Presumably they don't mean to disqualify Jupiter as a planet on the grounds that there are Trojan asteroids in Jupiter-like orbits.
