They’ve shown random peoples armies in White Dwarf before too, doesn’t mean they’re all 100% canon now. 

But it is still GW saying it's a cool army used for Horus Heresy and there is no mention about the Librarian (which they give highlight to) being in the wrong colour for HH. I would say it's an example of GW telling hobbyist: This is a cool army, you can do your army like this if you want to.
