Perhaps not the sense of vison, but the management of priorities. If the roll is making it hard for the crew to even hold their position in the cockpit and to maintain a semblance of control, then the roll attitude takes priority over the pitch. With a nose up pitch, the crew is being cradled by their seats. With a nose down pitch, gravity is trying to take them off the front edge of their seats. If PF was not using his shoulder harness, there was nothing for him to lean into, and he would find it was easier to hold himself in the seat in a nose up attitude.
From the Captain's perspective, the aircraft generally follows the nose in all his past experience. If the nose is above the horizon, then even though the attitude is not optimum, it shouldn't be falling out of the sky and he can concentrate on trying to make sense of the instrument displays. But if the roll was excessive and if he was not properly seated, he would be almost unable to function in any useful capacity.
