Why does it brew in the absence of the DRM code? Why would you ever design the null test be equivalent to the success case?!

The "DRM" seems to be a small led/sensor combination that tests to see id the lid of the K-cup fluoresces in a particular way. The clip obscures the sensor, and provided a surface with the right kind of fluorescence.

It's not the null test. The clip puts the minimal success case in front of the sensor 24/7.
