I remember hearing from a Yemeni American in the late 90s that the border with Saudi was not defined (mentioned in the article). I wonder if this could be explained more simply that a few sources didn't bother to update this over time due to the ambiguity, they just carried over what had been published before.
A casual review of the satellite view of the border with Saudi Arabia shows that much of it is desolate uninhabited sand dunes, so it's not like there's border markers such as the US/Canada have. Or likely an accurate survey (you'd need high precision GNSS equipment and something that can traverse serious sand dunes as a vehicle, because no fixed markers and traditional surveying methods have any chance of success there).
Historically, borders in inhospitable regions where the government cannot project power used to be vague.
Early Medieval European kingdoms usually had border forests, sometimes quite deep (50-100 km), where one end of the forest was definitely Bohemian and the other end definitely Saxon or Austrian, but the exact demarcation within it bothered no one.
There were only two kinds of people crossing them: invading armies and long-distance traders on very few walkable paths. The latter would be taxed prior to entering the city markets, not on the border. The former would be interested in sieging strongholds deeper in the enemy territory, not in taking a slice of wooded territory on the border.
