Narrative:

I was flying with 2 students for their night currency. We did 2 stop-and-goes followed by a full stop with the first student. As we cleared the runway, tower asked if we wanted to taxi back to the ramp. We replied, 'no, we would like to taxi back to runway 9L for more lndgs after we make a quick seat change?' the tower replied, 'roger, contact me when you are ready.' we then changed seats and began to taxi back to the runway. Tower could not see us, but warned us to watch for a cessna who was going to back- taxi runway 9L to the ramp. Tower then said he did not know where we were. We then turned our landing light on to help him find us. When we got to the end of the runway we informed tower we were ready. Tower cleared us for takeoff and we completed the flight uneventfully. When tower asked where we were it hit me that maybe they wanted us to call before proceeding with our taxi. I am still not sure what the controller was telling us when he said to contact him when ready (ready for takeoff or ready to taxi after the seat change). In the future, I will try and recognize poor communication and try to clarify it.
