That radio is there for communication: a close call

All went well, I reported final on 07, and was getting ready to perform a smooth touch down right past the threshold. Then, about one minute before touch down, I heard somebody saying something like, “LZPT taking off runway 25.” I was not sure I heard right. I mean, I just reported my final about a minute ago. Surely anybody on the frequency, let alone a pilot sitting in his aircraft about to take off, must have heard me?
