Keep in mind the AI's didn't know Church was the Alpha (Delta didn't, and Omega was in his head). And Tex was not a fragment of his personality, more like an imaginary friend AI... That's what I think. THe directors love for Tex made the Alpha create a sort of imaginary friend for Church during his high stress situations.
