The heretic geth still count. A hostile synthetic is a hostile synthetic, regardless of if they are willfully hostile, defending themselves, or manipulated. The results are the same.

Also, the Metacon War is an entirely different conflict with synthetics than when the Protheans destroyed the zha'til. The Metacon War was fought long before the Reapers arrived and allowed the Protheans to establish their empire over organics; the zha'til only became hostile after the Reapers arrived due to direct Reaper manipulation. I believe Javik implies that the Protheans confronted other hostile synthetics throughout their history as well.

And I hope Arbington won't mind me linking to a comment of his from another blog. I think its contents are relevant.
