Huh, apologies. I have a Dutch friend who has similar quirks in their English, and the article mentions Dutch by name (in "A Dutch operating system"), so I assumed the author was Dutch or that that quirk came from Dutch influence.
For what it's worth, Dutch is not the only language that does this, I'm pretty sure German does as well, and a bunch more. So you may be correct.
I think it maybe points to shared features of European languages that English doesn't follow.
