Thing is, he did not mention a lot of things. How did he get the scar, how did he obtain the stone and the armor, this might have been one of them. Why would he mention his "Wait, I could try to get back to the time, where there was not another me, it is  very unlikely that I will suceed, but I would still try to be completely sure. Yeah, I can not, just like I thought.  " I'm pretty sure that Savitar's original timeline got erased once he traveled back in time to help defeat his future self. It basically works like this:

Timeline 1: Barry fights against Savitar, he notices that no future version of himself has appeared to provide him with assistance and travels back in time a couple seconds in order to assist his younger self.

Timeline 2: Barry (now Barry 1) arrives to assist his younger self (Barry 2) in the fight against Savitar. Due to Barry 1's presence, Barry 2 does not travel back in time in order to become him (essentially breaking what would otherwise have been a stable time loop).

Barry 1 cannot return to his timeline, because he erased it when he traveled back in time in order to assist his younger self. I am pretty sure, when a speedster creates a time remnant, it is the future self, who becomes the main self, and the past self, who becomes the rime remnant, not the other way around, but you are right, the original timeline of the time remnant of the speedster  is erased.
