Does this imply that the expected irradiance of any given point location on a surface is 0? Similar to the way that the probability of a ray hitting a point in continuous space is 0.

To archshift: No; irradiance is defined as a quantity for a surface point. It can be nonzero. This is clarified in the equations on slides 39-41:
