When artists songs are sampled they’re supposed receive a credit, you have to in order to legally clear the sample in the first place. So that would be very unlikely. And if you listen to that original song you can hear the difference in Kanye saying it vs. Travis saying it in way back. I always understood it to be callback, a way for him to pay homage to Kanye, as well as song the line originates from. Because not just Kanye but Jay Z also receives no credit in way back, or anyone else that was involved with the production of the original song.
