Someone asked about this on quora, the first reply was this (from "Archie D'Cruz" fyi)

" the biggest difference here is that the story on the left was written after Donald Trump’s visit to Mexico, and the one on the right was updated after his speech late that evening in Phoenix."

A bit further in his post he said this

"It should be noted that many major newspapers (including the WSJ) regularly publish multiple editions. Some of the publications I have worked at did this because of distances—early editions were destined for areas outside the city, and making the newsstands in time meant pushing one edition to press a couple of hours before the main city edition. At other times, major late-breaking stories would be captured in a third (or fourth and fifth) edition."

So I think this provides a bit more context, otherwise yeah it would look very bad.
