Not true. It's just harder to connect shots to the head's hitbox when they're parachuting, but still possible. I see deformed zombies getting knocked back by scout headshots in the air all the time on ZM. On ZE, there are no chutes (and the stupid increased knockback thing is enabled anyway) so it doesn't matter.
