That's most likely due to Twitch's passive.

If Kalista stacks her spears, they won't deal damage until Rend. Twitch will constantly deal true damage, then physical expunge, and then continues to damage you until the poison runs out.

Even if he could add unlimited stacks that deal damage capped at 6x base poison stacks, he would still have the advantage of additional (true) damage over time.
