The directional capsules of the tetrahedral mic are responding to a
combination of pressure and velocity - that's how directional mics work.
The way their outputs are combined to generate W, X, Y, and Z serves to
isolate the pressure signal (W) and the velocity vectors (X, Y, Z) by
cancelling out the unwanted parts in each case.
