Commentary for Avodah Zarah 70:14
ואב"א אפי' תימא דקבעי לה לגבינה איכא דקאי ביני אטפי:
Or if you wish I can say that even if he wants the milk for cheese [the test is not conclusive because drops of milk] remain between the holes.
Daf Shevui to Avodah Zarah
Even if he wants the milk for cheese, the test might be problematic because even if all of the clean milk does curdle, there might have been unclean milk in it and that milk would remain between the holes of the cheese.
