I guess then remove the "if necessary" part?

After the modification of #10093, I think we can simplify the code because it's forced that we pass in one of the case tested by the "if":
tps.size == 0then we pass in ittpsand one element infps(tpsandfpshave the same size)Then the first point is the first classified positive so it's either a true positive or a false positive. So I think we should pass in the "if" statement in any case
