I would say these stamps are truly coupled as the Belgians like the Germans were most methodical in their procedures and application. The Calibrator applied the stamps, as well as cobbled together the proof load or approved the proof cartridge, and this was his job. He/she was a very proud lot & took their task quite seriously. Although the font is indeed different, I again say the Calibrator applied the encircled marks in one effort & then the Inspector applied his mark.
