Why high background strength with negative exposure?

I've already turned in the assignment, however I'm curious why you set a really high strength (25) for the HDRI but then compensated with a negative exposure (-3)? I recall something similar being done in the lighting fundamentals course, but can't remember why -- also, I don't see the point? What does this approach allow you to do that normal/lower values can't?

PS. Thanks for the awesome course! I learned a lot, especially about building a better glass shader for Eevee.
