Because they aren't?

If in one terminal I say "./a_program" then a_program is a process
running under the OS. It may contain many Ada tasks. If in another
terminal I say "./another_program" then another_program is another
process running under the OS, which may contain a whole lot of Ada
tasks, which know nothing about a_program's tasks. OP wants to ensure
exclusive access to a file between the two processes.
