What is even the point of crossfire?

Scenario 1: Warframe...

So, I saw that Warframe was not running crossfire, I go into CCC and select 'Optimise 1x1' to see how it goes... Crap, massive frame stutter whenever anything loads, fps is less than 1 card.

So I chose a predefined profile and see Warframe has one, select it, second card fails to do anything, running on 1 card...

 

Scenario 2: Skyrim SE

'Optimise 1x1'... Crap, 30fps 60% utilisation on each card. (as opposed to 50fps on 1 card at 90% utilisation)

So I chose a predefined profile and normal Skyrim has one, only 1 card works, I try another profile suggested by the internet (assassins creed brotherhood), only 1 card active...

 

From what I can tell is that the "crossfire" predefined settings basically work by not using one of your cards... When does crossfire actually work? Does anyone have a working example where crossfire give them better results than a single card? I'm yet to have that experience, as EVERY game I play has some sort of issue with crossfire... So why is it even a thing? I'm yet to even see a "crossfire setting" where crossfire worked...

As far as I can tell my second cards acts as poor converter where you spend frame rate for less utilisation of a single card.
