I did the line-of-sight calculation. Unless you want to dispute Euclid as well as the designers of the procedure (and I have utmost respect for those designing procedures for some of the airports in the fjords and in the Alps), it is not a case of "who knows".
According to both charts available at 1800 feet at the MAPt there is a direct line of sight to the threshold. That the video shows mist in the vicinity of the airport gives a reason that appropriate visual references could not be seen far more likely than a serious error in the design of the approach that no-one else has reported.
