The idea of the prints is that, if you submit prints, they are guaranteeing that they will be able to figure out who you are and approve you within 90 days. If you don't submit prints, they're saying that if they can't easily figure out who you are, they might need an extra 30 days. By submitting prints you are ensuring that you will have it in 90 days no matter what, but not that you will receive your app before anyone else.
