I do think this is a qualitatively different case from those covered in Expelled. It really amounts to a public university using complete acceptance of every contention of evolution, and complete rejection of even Catholic-style theistic evolution, as a litmus test for hiring in any area of science.
Moreover, it’s being applied selectively. I’ve known some quite distinguished physicists to express critical and often profoundly ignorant sentiments about some biological theories. The snottiness of some physicists about other fields is quite legendary.
For his sake, I hope his case is qualitatively different from the bunch of whiners in Expelled.
