Pies are defined by their crusts. A filled pie (also single-crust or bottom-crust), has pastry lining the baking dish, and the filling is placed on top of the pastry but left open. A top-crust pie has the filling in the bottom of the dish and is covered with a pastry or other covering before baking. A two-crust pie has the filling completely enclosed in the pastry shell.
Regular pizza is bottom-crust, calzone is two-crust. That’s my interpretation.
Pizza is either toast or a sandwich.
Edit: So yes, I think you’re right.
Why does this make me laugh but also feel angry?
If you fold a big New York slice, it can also be a taco.
This giant taco tastes like Italy!
Reminds me of your mom!

topologically I only see 2.5 options here.
So a hot dog is a taco, and a burrito is sushi.
Most burritos I’ve had have the ends folded in which may make them a calzone
I see a lot with one end open, other end closed, which I guess makes them a soup or salad?
Pretty self-explanatory.
It’s a pie. Your chart is missing pie.
A pie is just round toast or maybe round soup/salad/bread bowl.
Regular pizza is bottom-crust, calzone is two-crust. That’s my interpretation.
