Perhaps he meant that, like Oddwen said, Anduril is only dangerous against evil beings. This could prove that although Aragorn believed that Gandalf was evil and had the intent to harm him, Anduril "knew" that Gandalf was not evil and therefore could not hurt him. It could also mean that Gandalf could defeat Anduril because it is (for lack of a better word) a "good" weapon and not an evil one of the same potency:
