The F-15 has a rate-based automated flight control system, meaning it provides whatever input(s) from a variety of control surfaces as necessary to achieve a desired output (in this case, zero roll rate). In contrast, a rule-based (or fixed-mapping) system would assume that, for example, X amount of aileron displacement would give Y degrees of roll, and would not be able to adapt to the situation to over-ride the fixed input mapping. The Eagle's AFCS just kept on feeding in positive angle-of-attack on the starboard stabilator until it was able to offset the negative roll moment induced by the missing wing.
That in no way is meant to diminish the acknowledgement of the cajones that the pilot had in conducting a good controllability check and screaming in over the threshold at close to 300 knots!
