Rather neat to see this type of work being carried out, even though the final results may not have revealed anything major. I'm not so sure if I really agree on the heat transfer coefficients being "paradoxal" though, not too hard to see how the clay coat both provides better nucleation possibilities for the steam (helping cooling) and insulation through its thickness, resulting in just the behaviour they measured.
