Baked some pizza in a Milchig oven, then 10 minutes later baked some potatoes in the oven on 500 Deg.
Now someone who is Fleishig wants to eat the Parve potatoes, is he allowed to? Meaning these potatoes are coming from a milchig oven that had pizza in the oven 10 min earlier then had those potatoes baked 10 min after the pizza was baked.
