Would you rather have very hot air flowing into the wing internals through a crack/hole, or gas flowing outwards? Once the hot air begins to move inwards, it progresses to failure, assuming the flow is sufficient to erode the passageway. A positive internal pressure should prevent this initial inward flow if the crack/hole isn't too large.
