Plus, I didn't get the feeling that at any point during the fight with Emet did he seriously consider the possibility that we could actually beat him, on his (reconstructed) home turf, and at the peak of his power. At least, up until Ardbert did his merger and we hit Emet with the Axe of Light. Exemplar among mortals we might be - and seven (eight) times rejoined, at that - but we're still just a mortal. Again, Ascian overconfidence.
The question remains as to why he didn't bamf on out of there when it was CLEAR he was overmatched - say, the moment when we were actively charging him with the Axe of Light. At that point, there's any number of handwaves available: he was too drained from the fight, or he was reeling in shock from the glimpse of the Ancient within us, or the bamf process requires some kind of preparation, or merely the presence of so much concentrated Light power was restricting the use of his Darkness power.
In short, given what we know of Ascians, of Emet, and of the situation at hand, it's not at all surprising that he would have gone for the two in the bush (G'raha's knowledge AND WoL-turned-Sin-Eater) rather than the one in the hand, even given the (in his mind ridiculously slim) chance of disaster. When disaster struck anyway, there's any number of explanations as to why it was too late to do anything about it.
