He gets it--rather lucky timing, all things considered.

Loghain's tactic, thus far, has involved incapacitating as many of the armed, armoured, and shockingly dextrous walking corpses as possible--which means going for the knees. If he can't kill the bloody things, he can at least make it harder for them to kill him.

Kicking one clawing corpse free of his leg, he lets out a taunting shout towards the others that are crowding around Anders and Nathaniel, which has the desired effect of drawing their attention back towards him. As they lurch and lumber towards him, he readies both sword and shield, preparing himself to face the onslaught with gritted teeth and fire in his eyes.
