Neither. Signatures only contain the key ID of the key making the
signature. When displaying signatures, GPG shows the primary UID of
that key at display time. In other words, if you sign a key with one
primary UID, then make another UID primary, the display will change to
show the new primary.
There is, incidentally, a way of encoding which UID the signer "meant"
the signature to be from. It's part of the OpenPGP standard, but no
software that I know of actually uses it.
