Well, Yes & No. Your personal-preferences are just that. These are the ciphers & digests you prefer using. When Encrypting to *one* other Key or Many, GnuPG will compare Your preferences to the ones the recipient(s) have indicated on their Key are theirs. GnuPG will then accommodate all Recipient(s). In your example the message would be Encrypted using Twofish. This is because you are doing the Encrypting and this is what You *prefer* and the recipient has shown that s/he can handle Twofish. Should they click 'Reply' and email you back, it would be Encrypted using AES since they are originating the Encryption and that's their preference and you have indicated you find AES acceptable. In the case of multiple recipients/Keys, GnuPG will determine the common denominator. This is why in large Group Encryption environments you will most likely see SHA1 used as the Hash. It's "common" to every engine. In encryption you will generally find 3DES used as the cipher for the same reason.
