If I understand you correctly, you are right,
In critical phases where Prasit Drag is high and runing engine is used to its peak values, Sideslip drag is intended to be zero. In other cases like in cruise, assuming you are flying manually, you have two option:
1st OPTION: Maintain wings level, stop heading drift with rudder (apply to good engine side), so you can maintain constant heading. Index (yellow) is definitely aligned with sky pointer. Flying technique is relatively easy, but relatively more drag occurs, becasue sidelip is definitely not zero; RW is hitting from failed engine side.
2nd OPTION: Maintain slightly bank to good engine side, apply relatively less rudder than 1st option to good engine side to maintain constant heading. Index (yellow) definitely slipped slightly to bank side. Flying Technique is relatively difficult, but definitely less drag occurs than 1st option. Sideslip is definitely less than 1st option, but is it zero? Nobody cannot know, because sideslip (AOS) is not displayed to pilot in blue (betatarget) format.
