They are
non-precision approaches and don't have to be flown using a constant glidepath to normal touchdown point. The MAPt for the approach in question is at the threshold, and it's permissible to fly a level segment after reaching MDA. With 3500 m of runway in a small aircraft, it doesn't seem unreasonable to do so, or perhaps to set your intended touchdown point 1000 m into the runway so that you reach MDA about 1200 m from the beginning of the lights.
It's with that in mind that the AIP minima are set. If your company flies them using a constant glidepath to normal touchdown point, then of course a minimum RVR of 1200 m is pretty daft.
