Several calls to expected method on multiple instances fail

I've found that if an instance created several times, than its expectations do not work.

Note the code below. It will fail - "Init" will be actually mocked just once instead of requested 3 and thus NotImplementedException will be thrown. The same with ExpectAlways(). If you set int count = 1 then it's ok.

namespace ClassLibrary1
{
    using System;
    using NUnit.Framework;
    using TypeMock;

    public class Class1
    {
        public static Class1 Instance
        {
            get
            {
                Class1 cl = new Class1();
                cl.Init();
                return cl;
            }
        }

        private Class1()
        {
        }

        public void Init()
        {
            throw new NotImplementedException();
        }
    }

    [TestFixture]
    public class Class2
    {
        [Test]
        public void Test()
        {
            int count = 3;

            Mock mock = MockManager.Mock(typeof (Class1));
            mock.ExpectCall("Init", count);

            Class1 ins;

            for (int i = 0; i < count; i++)
            {
                ins = Class1.Instance;
            }
        }
    }
}
