I could be wrong here, but I thought it was because Ryuko had both halves of the scissor blade as opposed to just one. Maybe it's because you need to be holding onto both halves for it to completely stop life fiber regen. If you look closely at episode 12 (Spit Your Sadness Away) Dr. Matoi is holding onto both halves of the blade when he cuts Nui's eye out, maybe that's the reason her eye never regenerated (or at least I assume so because she still wears an eyepatch over it).
