I think the fog is getting clear, now. For every reaction going in, the fog will coat the exhaust too. For every action, there is that backwash when the intake opened and upon close there is a tiny push back up the throttle body. So both valve sides are fogged as are the rings. Fog to the valves, but settlement [after] to the rings are no longer under the kinetic push of the air against the back of the ring.
Watch the air flow past the ring, what is the difference you displace it with liquid? So look at the top of the piston. Air is going to be forced on top of the piston; move down the wall and side of piston; hit the tiny groove of gap where the ring sits and spins around, the building pressure is now forcing the air behind the ring in the groove; the pressure forces the ring(s) out due to that behind the ring that causes more sealing pressure besides the ring's own tension; the air is now under the ring so it escapes to the next groove behind the second ring; they float in between that air pressure; the spinning keeps the grooves clean so the rings can float in that machined gap.
When there is no air pressure left; the piston ascends upward after that power stroke; the ring(s) now sit on the bottom groove... Or you can say where the ring 'lands' is called that part of the piston. So from ring groove to where it lands sitting on ascend or descend, that ATF is going to run inside that groove and displace the air gap. The air gap can cause condensation; reacting to a chemical reaction between the ring's metal and piston's aluminum dissimilarities, cause a crystallized action to jam the rings closed by taking up that tiny air space; not spin in the grooves; block the air pressure to move behind the ring to seal = Low to No Compression!
That's why you use that thin oil to displace that air gap so that chemical reaction does not occur.
