why does setElementVisible not work for blips?

[IIYAMA]

        addCommandHandler("createInvisibleBlip", 
        function(player) 
            local blip = createBlipAttachedTo(player, 0, 3, 200, 200, 200) 
            outputChatBox("hide blip ".. tostring(setElementVisibleTo(blip,player,false)),player) 
        end) 

Returns true, but result is incorrect. If I can't set the visibility, it should return false instead of true.
