Would there even be a need for any such logic? The LOC is getting more narrow closer to the runway (and ground), hence the FD-AP (do not remember which one) gains need to be adjusted to avoid over-controlling. I think this may not apply to the internal guidance at all.

Two more thoughts:
while the sequence described by vilas is perfectly fine, I reckon the type rating course will demonstrate LOC+FPA for this excercise.
Secondly, is there an agreement on how close is too close, so that the AP needs to come off? I always guessed 1500 ft-ish.
