OLEDb.RetainSameConnection. Transactions...

Hello guys!

I have some troubles with understanding how transactions behave when "RetainSameConnection" is set to TRUE for an OleDb Connection.
Initial data:
   - SQL Server:
      - SQL Server 2008R2 (RTM);
      - A database called "Test" on the Server;
      - Three tables utilizing the same structure: tFirst(Col INT NOT NULL), tSecond(Col INT NOT NULL), tThird(Col INT NOT NULL)
   - SSIS:
      - The package has the next structure:
         - Connection Manager to the database "Test" (OLE DB Connection, Provider = Native OLE DB\SQL Server Native Client 10.0)
         - ConnManager Properties: RetainSameConnection = TRUE;
         - Some "Execute SQL" tasks, a "DataFlow" task and a "Script" task.
      - The purpose of the package is to (the pack is to demonstrate the issue and such a structure is selected intentionally):
         - truncate table "tSecond";
         - truncate table "tThird";
         - insert every row from tFirst into the tables "tSecond" and "tThird";
When the package starts, a transaction begins.
   1. Within the transaction the tables "tSecond" and "tThird" get truncated.
   2. For each row from "tFirst" insert the row into tSecond, tThird;
   3. Write @@TRANCOUNT to a local variable "intTranCount", then show "intTranCount";
   4. Commit the transaction;
