You're letting the two screens confuse you. They have no impact on the problem at all. It's the same thing as having two windows on the same screen, as far as the program is concerned.

Most likely, it's just one program that creates two separate windows. When you do something in either window, it changes some data within the program, then both windows are updated to reflect the current data.

They're not two applications, they are one application that has opened (and owns) two windows.
The two windows can be placed wherever you like just like any normal single-window application.
