Range increases don't apply to Holy Word's unique AoE, as far as I know there are many other odd Basic Attack patterns that can have range increases such as Firthrower or Anchor Edge's range.

I don't think it'd be a big deal either since realistically only Volley and Volley formation should apply.

It is not intended to go beyond its specific range so this is not a bug, unfortunately.
