There is only one document internally => So both tabs are updated 
synchronously.

Type in one, and you will see the changes happen in both.
Make changes in one, go to the other, and press undo => it will undo the 
changes you made in the other tab => since the changes where made to the 
document, and since both editors share the same document.


If anyone wants to keep a "history", that is what (IMHO) backups are 
for. save to a backup file, and open the backup file.
