Well I understand that if you have only two tabs title there. But, imagine for a second for people who have more tabs. It will be faster to rotate those tabs from end to end. Let say you at tabs no 5 on 6 tabs system. To get to tab1 you just need to move->6->1. 2 Steps instead of 5->4>3>2>1 5 steps.
