Transaction and functions

We are using functions in a single .p-file, like the following:

myTest.p

BLOCK-LEVEL ON ERROR UNDO, THROW.

FUNCTION secondFunc RETURNS LOG ():
   UNDO, THROW NEW Progress.Lang.AppError("ERROR HAPPENED, UNDO ALL!").
END FUNCTION.

FUNCTION firstFunc RETURNS LOG ():
   secondFunc().
END FUNCTION.

FUNCTION starter RETURNS LOG ():

   /* start transaction */
   DO TRANSACTION:
      firstFunc().
   END.
END FUNCTION.

/* start execution of the function tree */
starter().

CATCH err AS Progress.Lang.Error:
   RUN WRITE_log(err:GetMessage(1)).
   MESSAGE err:GetMessage(1) VIEW-AS ALERT-BOX.
   UNDO, RETURN ERROR.
END.

According to this code, does the Transaction undo all changed done inside it in starter()-function? Or do we need to pass some kind of handle to all functions inside the Transaction so it can be "undone"?

If an "outer" transaction rolls back then all sub transactions, including those in called code, will also roll back.
