I didn't know that scenario but I certainly could see it happening. Oxygen under enough pressure becomes a pretty nasty oxidizer. Especially when it happens suddenly. (Open the valve on a high pressure oxygen tank, pressurizing a system that wasn't previously pressurized.) By the time you add enough heat to the mix--rocket engines always run fuel-rich because at those temperatures an engine that runs oxygen rich probably then runs engine-rich. If you burn an engine to fuel exhaustion you likely destroy it.
