I feel like you're posting this as evidence to the contrary, and if this is the case then you're misinterpreting the scene and the very text you posted
Yes, Asuka kisses Shinji to get back at Kaji, but no one kisses someone they don't care about out of the blue
It's kind of the point, she makes a big deal about only wanting to do it out of boredom because it's an absurd excuse, and obviously not true
And later on you can see that his lack of a reaction hurt her deeply, had it been only about Kaji she wouldn't have been nearly as affected
