If you pay more attention to what the page is telling you, it is explicit that it is BONUS damage only. The vast majority of autoattack modifiers use this convention and do not list the base ratio.

There are a few attacks that will list total damage instead, like Poppy's Q, and these DO list the 100% AD ratio, although they are usually special cases (with said example, the entire attack is magic damage so it's not obvious that the base autoattack is factored in or not).
