Well, the best I can tell, the starfish exposure to air is mostly myth which seems to be rather pervasively perpetuated on many sites.
It seems there is some questions around certain species to maintain Osmotic stability when exposed to air, but generally no issues arise until after 1-2 hours of exposure.
That said, I do not feel because I looked into a little further, I am now an authority figure on the subject. So I am open to contrary information.
It is a myth, though I would not expose them intentionally for long.
It likely stems from trying to explain the high mortality rate of seastars in captivity. But this is more typically due to inability to adapt to synthetic salt mixes, improper acclimation and osmotic shock.
