Alright, this following comment is
not an official communication by Kiwi.com, it reflects solely my personal guesses/opinions.
I'm not sure about the details since I don't have much to do with the legal side of things, but I would assume that Kiwi.com had to put this clause in to avoid having to pay when a flight's price is 1000x higher than it should be as an error fare, or similar cases. I've personally never heard of a case where expenses weren't fully covered because of this clause.
