That will be one of the very first suspension forks, so it predates 'suspension corrected geometry'.
1988 RidgeRunner with early radical fork in ski lift:
I am pretty sure this is Gerrit Gaastra's bike. He is member of the familly behind Batavus and later Koga-Miyata. In the early 90s Koga was sold to Atag Holding. Nowadays it is part of the Accell Group - Europe's largest bicylce manufacturer. Gerrit Gaastra initiated idworx.
Gaastra had a column in Holland's 1st MTB mag: AllTerrainBike Magazine. From Canada, where he lived in the late 80s, he wrote about the latest MTB innovations. I wouldn't be surprised if the ties explain why the early 90s Koga mountainbikes (and even roadbikes to some extent) came specced with Syncros everything.
