The mechanism for E is well known. In experiments in rats, giving them vitamin E allows them to store 4.5 times the amount of vitamin A in the liver. Peat said that vitamin E prevents vitamin A from "being destroyed", I think it has something to do with the issue that vitamin A is unsaturated.
The adrenal glands store the greatest amount of vitamin E of any organ per gram of the organ. They also store vitamin A, so I guess it also improves storage and use of vitamin A in this organ.
Chris Masterjohn suggested a mechanism by which K2 might spare A. Don't remember, but I supplemented with K2 and got incredible reductions in my need for vitamin A to control skin symptoms, much more than what I got using vitamin E alone.
