Guys, please look at the following question

I am aware of how to take a dot product of 2 vectors whose i,j,k components are given. My issue is with both integrals. I feel it should be '-dx ' rather than dx because x is decreasing , same as in '-dy'.and I'm taught that if x is decreasing then we should take '-dx' , but why is it not so . Please tell me why . I do understand that my questions are a little too fundamental but please answer them
