Indeterminate state cannot be either / or. Both states are feasible hence the word "and."

This point is described in Hawkins brief history of time. It clarifies why the cat analogy won over the original one that Schroedinger and Einstein cooked up together. Einstein back pedalled after reading a paper from Bose who was a young student in India who sent him a paper.

Mind you, pedantic discussion over indeterminate state in itself requires acceptance of Heisenberg and his uncertainty principle. All hypothesis and nobody gets killed for believing it.
