The AS Path isn't about where the update has passed through, but the same attribute, when signed, is a mechanism to provide security. And while the AS Path isn't about showing the path of the update or the traffic, when it doesn't match the new attribute that is supposed to show the path of the update this means there is an attack of some sort.
