They chose to use a standard so yes it's a problem that they didn't follow it. It's pretty cut & dry here.
Fortunately in this case it fails to 0V so it's not a dangerous or damaging failure, but still the spec literally hands you a schematic. Is it that hard to just copy it? Why did they even try to be clever and use their own design in the first place just to save a single 5.1k ohm resistor?
