Delegates and events.

i'm trying to understand delegates and events and wrote a simple app based on an example.

namespace DelegateTest
{
    public partial class Form1 : Form
    {
        
            BroadcastClass B = new BroadcastClass();
            ListenToClass1 L1 = new ListenToClass1();
            ListenToCalss2 L2 = new ListenToCalss2();
            ListenToClass3 L3 = new ListenToClass3();
        public Form1()
        {
            InitializeComponent();
           // wire methods of one class to the event of a single class
            B.EventName += new DelegateName(L1.IHeardSomething);
            B.EventName += new DelegateName(L2.IHeardSomething);
            B.EventName += new DelegateName(L3.IHeardSomething);
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {
            B.Start();
        }
    }
}

I then modified how i passed in the methods to the event (see below) and it still works. So i'm wondering why the the example is different and why my way works and is my way ok or is it wrong in some way. All examples use the above method.

namespace DelegateTest
{
    public partial class Form1 : Form
    {
        
            BroadcastClass B = new BroadcastClass();
            ListenToClass1 L1 = new ListenToClass1();
            ListenToCalss2 L2 = new ListenToCalss2();
            ListenToClass3 L3 = new ListenToClass3();
        public Form1()
        {
            InitializeComponent();
           
            B.EventName += L1.IHeardSomething;
            B.EventName += L2.IHeardSomething;
            B.EventName += L3.IHeardSomething;
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {
            B.Start();
        }
    }
}
