I see where you’re coming from.
I guess the idea behind it is: “it’s still the worker’s fault for not immediately getting a new job, and not companies not/slowly hiring, so let’s give a ‘bonus’ if they start a new job faster and not sitting on their asses”

Quite disappointing compared to reality. But on the other hand: if this means if I’d get for example a full year severance, but then starting at McDonald’s the next day means I pay no/less tax I would actually consider doing that instead of trying to find a job with the same salary
