No, it just affects the goto but not the tracking. Think about using a guidescope. It's common practice to move it around a bit to find a good guidestar, which is equivalent to mirror flop, but you still track accurately. With mirror flop, you will be off when you use the goto, but once you have centered the object, it should track accurately.
