There are two different densities of foam as well as two different foams with their own characteristics of recovery from impact and inter-foam bond strength.
In a crash, the impact force pushing towards the head causes the cones to compress which creates lateral forces spreading sideways through the higher density outer foam layer.
Impact energy/force is absorbed by this lateral motion. At the same time, the head is travelling in the opposite direction, compressing the base of the lower density cones and slowing the accelerating head.
The result is lower G-force experience for your head.
The benefit: a lighter helmet + softer protective shock absorbing foam closer to your head.
