"Gas" shocks still have hydraulic fluid in them. They use the addition of an inert gas (usually nitrogen) to extend/retract faster. The hydraulic fluid can aerate (foam up with air bubbles) under fast action. The Nitrogen under pressure keeps the air that is dissolved in the hydraulic fluid from outgassing and foaming up. Since air can be compressed (hydraulic fluid cannot be compressed) this would result in unpredictable shock operation.
