You're presuming that the pilots' actions actually caused the SOVs to close, they may not have. QANTAS A380 2010 could not shut down No 1 engine (undamaged). It ran for about 3 hours after the landing, until fuel exhaustion. EK A340 on the ground in Toulouse, engines ran for about 9 hours (?) until fuel exhaustion, but that was very different reasons. i.e. lack of access to flight deck.
