No, subway and panera do the same thing. Fresh premade dough is delivered every night, refrigerated. At Panera, a baker runs it through the oven overnight and finishes baking just before open. Subway throws dough in the oven as needed throughout the day, they have much higher volume.

Frozen dough doesn't come out the same, nor does reheated pre-baked bread. It's fresh it just isn't made from scratch there in the store.

There's a couple dozen fresh dough facilities scattered throughout the US that serve all of these restaurants that need fresh bread, but without the cost of paying someone to mix flour locally.
