Erm, but as admin has quite rightly pointed out, foreigners have to get out within a month (and for some categories, even faster) once they lose their job, including those foreigners with special skills who hold the equivalent of temporary PR while here. So you would always expect non-resident unemployment to trail resident unemployment by quite a large margin. After all, the alternative would be having more non-residents unemployed and by definition, just sitting around in Singapore doing jack ****. Which would you prefer?
