Could in-place op be fused

I try to figure out why the following code doesn’t fuse at all. I notice that the IrParser::registerJitOperator registers only the normal tensor op. Does it mean in-place op cannot be fused?

def calc(exp_avg : Tensor, 
         exp_avg_sq : Tensor, 
         beta1 : float, 
         beta2 : float, 
         grad : Tensor):
    exp_avg.mul_(beta1).add_(grad, alpha=1 - beta1)
    exp_avg_sq.mul_(beta2).addcmul_(grad, grad.conj(), value=1 - beta2)
