Hey gr4vity,
Graduate schools are weird.
Last year when I didn't get accepted into a college I applied to, they kept sending these nagging reminder emails about completing their financial aid, etc etc. Ultimately, I didn't get accepted, but for some programs, if you do get accepted, it's good to have your stuff completed because you could receive priority for funding/scholarships/and the like.
So, it's certainly not an indication of admission, but it won't hurt in case you do get admitted.
Best of luck!
