In time it will matter.
Salt doesn't get removed from soil very fast. Rain dilutes it. Your freshwater additive dilutes it. But dilution isn't removal. Eventually it will kill the area you are putting it. Hard stop, period, end of story. Its not a question at all of IF it will, it WILL.
The only question is how long you get away with it before it happens.
