You may be correct, however I can envision that there may be a conservation of angular momentum in back to back gammas stemming from the spin of the positron and electron. If the positron and electron are lined up with their spin vector parallel or anti parallel, then the gammas may emerge in a similar alignment. If there is no initial orientation of the positron and electron, I would agree with you.

They are extremely sensitive. IIRC, it was curious that the Bianchini results were slightly less than background. At the time, this seemed to indicate that whatever was going on in the reactor was creating a spatial zone of energy deficit for gamma radiation – which is just the opposite of expectations. From: Bob Cook Jones-- If the positrons were directionally controlled by the magnetic field, Rossi's meter may not have been able to pick them up. Bob
