RS ammo using AS principles?

Saw this today on reddit:

This part was interesting:

First of all, when the gun is fired, the vents supposedly allow the propellant gases to go through the sides of the bullet, providing lubrication between it and the inside of the gun's barrel.

It would appear that RS is going the direction of AS (assuming that this principle works); while we in AS have been trying to go the direction of RS... discuss!
