I initially thought it might be some async weirdness with the cleanup step of some tests being executed after another had already started, but as far as I can tell, jasmine handles that properly. In the same vein, I also considered that perhaps the global variables aren't always fully initialised by the time the tests are executed, but moving the initialisation into the beforeEach() step didn't seem to affect anything.
