Agreed, I have yet to be able to save both. And if you go up on the south west side and knock down the wall, jump the pile of rubble to save that one guy, then once you revive him he runs the wrong way out through the fire thus immolating him. And throwing water down only lasts for a few seconds then the fire pops up again.
I have been able to save both, but it's just not fun having to fight the mechanics of foisting an action sequence onto the sluggish UI, dialogue boxes and dice-rolling. I would save before entering the burning building and there's always a chance that Benryn gets blinded or gets himself stuck while following my party out of the building. I'd then reload and try again.
