Potatoes absolutely will build up enough internal pressure to pop, even if the skins have been punctured. Not every spud will blow up some just split; when they do it makes a hell of a mess in the oven. I once broke a microwave at work with a potato because it did this.
To postulate a reason; some potatoes have a higher moisture content than others.
