Difference between "Run outside sandbox" and "Trusted aplications"?

I mean in the settings.

File rating>>Trusted applications seems to be a place for user defined trusted programs, they run outside sandbox.

Sandbox>>Sandbox rules (Run outside sandbox) seems to have the same effect.

If I click “don’t sandbox this again”, the entry is created in both of these lists, but if I delete the entry in one of the lists, the other one remains (having no effect on the program, until you delete the entry from the second list).

This is a bit redundant, don’t you think? Or am I missing something?
