On the one hand, SaviBarry needs to kill Iris to make Flash try and stop him by making the time remnants, thus creating RemnantBarry. If there is no RemnantBarry made, then SaviBarry can't exist. (Even though he does.)
However, KNOWING that SaviBarry is RemnantBarry, it seems to me that all RealBarry has to do is NOT make time remnants to fight SaviBarry in the first place, thus uncreating SaviBarry in the first place.
This gets into the whole " "Go back in time and kill your own grandfather" effect, where, if you kill your own grandfather, how do you exist to go back and kill him in the first place" territory.
It also goes into something like: RemnantBarry becomes SaviBarry after being shunned by everyone else, so, knowing this, why can't everyone, well, NOT SHUN RemnantBarry, if he even does get created, thus, at least trying, to prevent his turn to being SaviBarry?
As was stated in the episode quite a few times, "cause and effect".
