No Polish Partition?

I recently played a game against the AI where the Germans didn't actually conquer Poland for a long time, IIRC it was November or December before they actually got Warsaw. It looks like the events triggering the partition of Poland into a German and Soviet parts simply never fired - aside from the fact that IIRC the AI will never take the 'refuse partition' option, there wasn't a spike in USSR readiness that should have happened. Shouldn't the partition trigger even if Germany lounges around not actually finishing off the Poles? If it does work this way, it seems like a viable strategy for Germany is to wipe out the Polish forces, but leave Warsaw unoccupied until late in the year so that the start line for Barbarossa is far enough to the east that you can put units on the border and not have them count for the "18 units within 10 hexes of Warsaw" hit.

I went back and looked at the event, didn't realize there was a 25% chance of the AI choosing not to honor the pact and that it's only a 20-30% jump. I hadn't encountered this before, but the AI refusing to honor the pact is probably what actually happened.
