Using TransactionScope Does Not Update Identity Column

I started using TransactionScope to help with my unit tests in order to return the previous state to the test base. Using this with SpecFlow, I have a base class:

public class TransactionScopedFeature
{
    private TransactionScope Scope { get; set; }

    [BeforeScenario]
    public void BaseSetup()
    {
        this.Scope = new TransactionScope(TransactionScopeOption.RequiresNew);
    }

    [AfterScenario]
    public void BaseCleanup()
    {
        if (this.Scope != null)
        {
            this.Scope.Dispose();
        }
    }
}

All of the above works, when I add records to the database, when I then query the tables after the tests are completed, these tables are empty. Great stuff and very smart!

My question relates to the identity columns in these tables. I noticed that when running multiple tests, the identifier column of my test table increases by 1. I assumed that since TransactionScope will roll back the changes, the identity seed will also be thrown back.
