I find it absurd that Yasuo wind wall negates Talon's ult completely

For the first time playing talon into Yasuo I can across the annoyance that regardless of the position of Yasuo's wind wall if it so much as touches a single blade from Talon's ult it immediately stops the entire thing.

Now I recall hearing this about a year ago on the boards, but the real question is why does it work this way? Like I understand that in the coding they have it as a projectile etc but realistically it's absurd that if the wind wall is to the east it ahouldnt negate all the blades going in the other 3 directions.
