Together is the opposite of seperately. The combination is signed. The one
signature is not valid for the key or the UID alone, only for both together.

The signature is accepted if it signs the combination of key and UID.

Correct. "Self-sign" refers to the key making signatures for its own
components in contrast to signing other keys.
