In theory, you'd think that the two functions would be exactly opposites of each other; it would seem that if it reaches the surface at a certain angle, the same angle would be reflected when it is exiting the surface. It's interesting to see the math and physics behind this surface radiance, and why exactly they aren't equal. Knowing this information, it is possible to make more realistic renderings, as opposed to making assumptions based on initial intuition.

would the incident and exiting surface radiance be the same for a perfectly reflective surface at the same area?

Incident surface radiance is the radiance of the light that reaches a surface before any interaction occurs, while exiting surface radiance is the radiance that leaves a surface after interaction with that surface.
