My point is that they're both enclosed, by deep frying and baking respectively, and usually cut in half for consumption. Where's the difference?

A calzone could be considered a hot sandwich maybe. But...

The Monte Cristo is bread that has already been baked. It's basically done being cooked, then it's fried as a complete sandwich.

A calzone is raw dough, just like pizza, and part of the cooking process involves the dough baking to completion.

Since sandwiches don't involve cooking raw dough as part of their preparation, I think pizza and calzones wouldn't fall into the sandwich family. The are close though.
