Well, Wikipedia also follows it.

And iPhone 8 is the predecesar to the iPhone XR, as both of them were the lower-end/mid-range alternatives to the higher-end iPhone X and XS (the 8 being the alternative to the X, and the XR being the alternative to the XS). It would explain why they are similarly priced. (iPhone 8 = $700, iPhone XR = $750)  Also, iPhone X and XS isn't the main line of iPhone released in their respective years, here's why:

iPhone 11 is clearly the main line of the iPhone in 2019 because of the name. And the iPhone XS is the predecessar to the iPhone 11 Pro, as both of them are the highest-end iPhones released in their respective years, and similarly, the predecessar to the 11 is the XR. So it makes sense that XR is the main iPhone released in 2018. And since the X is the predecessar to the higher-end XS, that would mean 8 is the main iPhone of 2017.
