...simultaneous AP failure is about as likely as both engines failing at the same time, not something to be too worried about I should think.
In the Nigeria accident the FDR shows both AP were on when it ditched. I'm curious why they were flying/hovering around for 5 minutes at 25 knots or less when faced with a malfunction so dire that required a ditching: you'd think the landing profile would be more timely (unless it's a recording anomaly with the aircraft engines left running for a few minutes whilst in marine mode). This together with the seven AP2 resets and two AP1 resets has me quite puzzled.
