תוס' ד"ה והא

And this which was taught Pohtur; where he took out half-a-Zayis from a large corpse - והא דתנן פטור דאפיק חצי זית ממת גדול

Summary:
It is obvious that by taking out a חצי זית (if that’s all there is) he is פטור. Removing a חצי זית from a מת גדול is פטור for לא אהני מעשיו; however for removing a כזית ממת גדול he is חייב, since he prevented the house from becoming טמא after the removal of the מת.
