Every point gets examined, regardless of where it sits. Points on the opposite side of the map get the same treatment as points right next to the query region. We're doing a lot of unnecessary work.
What if you create a truly unique routing profile that's wildly different from the common ones for which shortcuts were pre-calculated? The system is smart. If it detects that too many shortcuts (~50, for example) need on-the-fly recalculation and deviate significantly, it might determine that falling back to the original, comprehensive A* algorithm for the entire route would actually be faster than doing many small, heavily modified A* calculations.
