Yeah, but, stick shaker goes off too, and
assuming SMYD (which provides stick shaker) hasn't changed from the NG, it gets raw sin/cos signal for AOA which is what the sensor outputs, not the ADIRU.
Also, on the NG at least, the data acquisition point for AOA is downstream of SMYD, so we are seeing, in the traces, what SMYD saw/calculated, not ADIRU output.
Unless the MAX air data architecture is significantly different, but I don't think it will be.
