Need Blind School - Yet Know How I Answered the Question on the Common App

On the Common App it asks if I intend to apply for Financial Aid - Yes or No. How can it be need blind if they have these two categories? While the school will not know if I need a little or a lot as they review my application - they will know I need something (vs kids who say No to this question, who can cover 100% of the costs).

I find this confusing!

Got this answered in another Common App thread - THANKS
