With pushrod engines such as this, the hydraulic lash adjuster between the cam and pushrod can compress instead of staying stiff. The cam lobe pushes the adjuster up, but it compresses so it doesn't push on the pushrod hard enough to open the valve. The valve stays closed, both intake and exhaust, and the cylinder just keeps compressing/expanding the same combusted gas it had in there from the last combustion cycle.
