Would you put the second return statement in an else block?

OperationInfo.cs

public object Execute(Client<T> client, MethodCall methodCall, string signature)
{
    if (IsMapped && TryGetMappedOperation(methodCall, out var mappedOperation))
    {
        return ExecuteMapped(client, methodCall, mappedOperation);
    }
    return ExecuteImpl(client, methodCall, signature);
}
