To which signature is that result reporting if the verifier simply ignored one of them, and both of them had "d=example.com"?

If for example the signer included one signature with "l=" and one without, the verifier or A-R consumer might want to prefer one over the other, but it won't know what action to take if it can't tell which signature is the one that passed.
