If RACAL is to be believed at all, then the crew did a manual Waypoint change shortly before impact. They wouldn't bother if they had already lost confidence in the equipment.
Also if they were already dealing with a major catastophe like a FADEC runaway or a UFCM I doubt Waypoint Change would be high on the agenda.
Given the timescale, I think that the act of changing the Waypoint, caused, or at least drew the attention of the crew to another real or perceived emergency situation.
But, as you say, who knows?
