They are probably lying. I doubt anything is in orbit. NORAD knows for sure.
Now three years later they try again and they say it is in orbit.
Which begs the point if they will get caught up in their own lie which they may forget. (They lie so much it must be difficult to keep track of all of them so they dont contract later. There must be a Chief Section, Department of Lies to the Outside World, in KWP headquarters in Pyongyang.
Will they herald this as the FIRST TIME they have but a satellite in orbit(?)! Or will they say this is the second time?
Merits watching.
The US knows every inch this rocket traveled. They won't say because it would leak our capabilities.
