Edit... I just figured out, once again, that I'm full of shit. A nick in the rod isn't the killer. Duh. It's breakdown of the internal seal.

No... I take back my own correction. The gas seal really is around the exposed rod. Here's how we know this. If the gas was to be compressed fully between the face of the piston and had nowhere to go, it would behave like a bicycle pump with a plugged hose. It's not a bicycle pump. It is able to collapse with only a small increase in extensive force at the collapsed position. The extensive force equals the internal pressure multiplied by the cross sectional area of the opening upon which it acts.
All the internal parts are at equilibrium. The cross sectional area to be considered is the area of the circle projected by the axial view of the rod.
I'm guessing no one cares about my ramblings here. I'm just keeping myself honest with stuff I say in general.
