Most compression gauges I`ve seen have a schrader check valve to keep pressure from leaking out of the gauge sometimes there is a botton to release the pressure without messing with the schrader valve.If either valve was erratic it could leak out.Assuming there is no such valve on yours if your motor were to stop in the right spot your pressure would leak out instantly through the exhaust ports.If it were to tend to stop in a position near the ports it might leak a little.
