The primary goal here is to keep the decrypted output as similarly structured as undecrypted output as possible. Now, when decrypting parts, only the original encrypted part is replaced by the it's decrypted content. If this part isn't itself a multipart, then all part numbering should remain consistent during decryption. The only draw back here is that the useless application/pgp-encrypted sub-part of the multipart/encrypted part is also emitted. But this part can be easily ignored by clients.
