Tourist Visa for US Citizen with no long term residency.

When I talked with CVASC on the phone today, they called the consulate and got it affirmed that I would not have an issue with acquiring a Chinese tourist visa from the consulate in Hague as long as I had my proper application documents and a Netherlands entrance stamp on my passport. I assumed I was in the clear until an hour later when I realized my Schengen entrance stamp was from Poland, where I flew in. Does anyone have any information on whether that will also be okay or not? Or shall I need to leave the Schengen zone and reenter directly to the Netherlands? Any info and advice would be greatly appreciated!
