admittedly: i have no idea how the game actually calculates stuff, especially not AoE damage. that considered, here is my take on this:
the numbers should be correctly reflecting the patchnotes.
an aoe effect has to have a radius (not only for visuals, but also for damage calculations, if you take normal weapon damage calculations as a basis).
take this (awesomely drawn) pic as a reference:
red = near (inner circle, radius = near)
yellow = near-far (2nd circle, radius = far)
green = far (outer circle, radius = aoe_radius)
if you would only use the near/far numbers as a reference, calculating anything is this circle would be impossible, since you have no max_range indicator (which would be the radius of your AoE).
logic thusly dictates that, if the calculatins for AoE are similar to how normal weapon hits are calculated, the radius does affect those calculations too.
(if that wasn't the case, the outer circle would not exist in the game, except for "aesthetic" purposes. it would also mean that AoE calculation is significantly different from all other calculations, and that there are only 2 zones for AoE dmg/supp/acc/pen, which creates more questions regarding how that stuff is calculated)
