Observation: Network config related

while trying "alchemy-sdk" as a novice I had typed-

const config = {
    apiKey: process.env.ALCHEMY_KEY,
    network: Network.GOERLI,
};

instead or

const config = {
    apiKey: process.env.ALCHEMY_KEY,
    network: Network.ETH_GOERLI,
};

what i observed was that I was able to retrieve my main Net information.
shouldn't I be getting an error?
