I don't know how Pinpoint does it either, but it is obvious how it could be done dynamically without a model.
How would this be any more accurate than astap (without distortion correction)? It seems that with or without distortion the platesolve would be able to determine precisely the RA/Dec coordinates of the center of the frame. Considering any detrimental impact from distortion would presumably be centered precisely around the center. (Yes, I'm using Roland's definition of distortion for this logic).
It would be interesting to hear Han's take on this aspect of ASTAP.
EDIT: I'm most interested on whether it would even make a difference for a 10 min unguided exposure. I.e. a practical use scenario.
