I've never heard a definitive answer. Again - it's probably the slightly different chassis/wheelbase and less rear overhang. In high-stress situations everything matters.

There is a longer distance between A pillar and B pillar support in the coupe. The vertical support is more evenly positioned and anchored in the sedan. That should also have some effect.
