If "Titi" and "Toto" are both yourself. why is this an issue?

If "Titi" and "Toto" are not the same person but are sharing a secret
keyring, they should both change their passphrase and (ideally) stop
sharing a secret keyring.

GPG makes no guess at who is there, it only knows if the correct
passphrase was entered for the key it wants to use.

- --local-user defines which key to sign with.
- --recipient specifies which key to encrypt to.
