Yes, I'm aware they have the same voice provider (Asami Shimoda), but they do not have the same voice base. Asami is a very skilled voice actress, so she recorded one voicebank in her Rin ("Natural") voice, and one in her Len ("Boyish") voice. Rin and Len do not share voice samples or anything like that. The same goes for their Appends and the upcoming V3 update.
