It also asks to respond with a decision regarding acceptance by Feb 18th if possible. Did any one else's scholarship information say something about this?
There was a similar deadline on mine last year. I called and explained that I didn't want to commit to a school until I heard back from everyone about acceptances and scholarships (obviously). We established and re-established the "deadline" several times.
I think many OU applicants only apply to the in-state schools, and OU is their top choice, so they know right away whether they will be accepting or not. However, is it not very practical for someone applying to out-of-state or higher ranked schools (that you don't hear from until March or April), and the scholarship committee understands that.
