Probably the same reason why he chose to lie about the Kyuubi attack on the leaf to be a natural occurrence. As the ramifications of that incident directly led to the suspicion, isolation and eventual Uchiha massacre. All to rile up Sasuke and push him over the edge. Consequently, the Izumi-line paints an even more tragic picture of Itachi, for Sasuke to be affected by.
