for Pune-Mumbai trains the same pilot will work the train back in reverse direction. That may not hold true on all legs of TVC Raj's run.
For short stretch duties, like BCT-ST or PUNE-Mumbai, duty means running train in either directions. For that of TVC Raj, on other hand, duty would mean single run, for ex from Vasai road to BRC or From Ratnagiri to Vasai Road.
