This is crazy! I've never heard of that before. So the mineral oil is leaking through the pistons, into the pads (but only the face that touches the rotor or you couldn't sand it off) but from the front, not the backing that actually touches the pistons? That sounds like some interesting 'science'. Why wouldn't it just be the metallic pads oxidizing over time? Leave bare alu out and it forms a layer of oxy- why wouldn't this be the same for whatever sintered metal compound brake pads are made out of?
