If you go to the source for that article -
https://9to5google.com/2019/09/20/irish-retailer-leak-pixel-4-prices/ - they actually put "unreliable prices" in the title. Further down they comment how "at this one single retailer, in a currency that is not USD, the Pixel 4 is cheaper than the Pixel 3"
I would expect the 4 & 4 XL to be right in line with the competition and, if Google is smart, they'll take the small hit of scorn by those who bought the 3a and 3aXL when it came out 6 (?) months ago in launching the 4a / 4aXL as a mid-price at the same time. Otherwise, the general population will be hard put upon to accept the 'entry level' Pixel being introduced as worth such a premium over the basic iPhone 11.
