Considering different groundsettings for these messages:
HIU HKQ (where similar letters were known as (1,4) ,(2,5) females etc.
I think the cipher clerk rotated the rotors based on the groundsettings with an offset of the 3 for the 2nd enigma in a pair. While that might produce the same letter in each enigma in a pair whether Bomba gives an accurate result of rotor order and ring settings. In other words can bomba still halt but give you different settings other than the one Germans used.
