Really? Bernina has their own refinery and chemical lab? I would think it more likely they have certain specifications and contract with a vendor to be supplied with an oil that meets those specifications (which is likely no different than any other sewing machine oil, except perhaps they have outlined trace impurities in their spec more than other companies in order to call it "Bernina-approved".
