Except they don't tweak weights when the model is incorrect, I'm puzzled why he's making that claim?? In equation 32 they show weights are adjusted in the form `dW = K * S * (Wmax - W) * F(A)`, where F(A) is the feedback given the chosen action A (i.e. reward). K is positive and S non-negative, so Weights can be nudged towards a maximal absolute value Wmax in the direction of F(A).

However, they set `F(A) = {1 if A is correct and 0 when incorrect}`. That means weights don't change when the model is wrong and can only be potentiated (`sign(Dw) == sign(F(A)) == +`)
