SqlCommand-SqlConnection Using Disposing issue

According to MSDN If the IDisposable resource of the nested inner using statement contains the resource of the outer using statement, the Dispose method of the nested resource releases the contained resource.

MSDN (http://msdn.microsoft.com/en-us/library/ms182334.aspx) =>

Example Nested using statements (Using in Visual Basic) can cause violations of the CA2202 warning. If the IDisposable resource of the nested inner using statement contains the resource of the outer using statement, the Dispose method of the nested resource releases the contained resource. When this situation occurs, the Dispose method of the outer using statement attempts to dispose its resource for a second time. In the following example, a Stream object that is created in an outer using statement is released at the end of the inner using statement in the Dispose method of the StreamWriter object that contains the stream object. At the end of the outer using statement, the stream object is released a second time. The second release is a violation of CA2202.

But if i try this piece of code the code still works and returns the number count inserted into the table. Which is contradictory towards the MSDN explanation. I would expect the code to crash on the cmd.ExecuteScalar() call because the conn variable is disposed after the first inner using statement. Why is this still working and why isn't the conn variable disposed after the first inner using?

static void Main(string[] args)
{
    var numbers= DoItGetIt();
}

private static int DoItGetIt()
{
    using (var conn = new SqlConnection("Data Source=BestmixSql;Initial Catalog=Test;Integrated Security=True"))
    {
        conn.Open();
        using (var cmd = new SqlCommand())
        {
            cmd.Connection = conn;
            cmd.CommandText = "INSERT INTO [Test].[dbo].[Tabel] VALUES (666)";
            cmd.ExecuteNonQuery();
        }

        using (var cmd = new SqlCommand())
        {
            cmd.Connection = conn;
            cmd.CommandText = "SELECT COUNT(*) FROM [Test].[dbo].[Tabel]";

            var count = cmd.ExecuteScalar();

            return Convert.ToInt32(count);
        }
    }
}
