At least twice, maybe three times in my career, I have had airplanes, namely the 737, below a GS, all-of-sudden, while on AP, lurch up to grab the GS. May not have been 30 degrees but it was an unusual attitude requiring quick disconnect of the AP. It happens. The ILS in Quito Ecuador is notorious for a moving GS signal. An airplane on AP is in for an undulating ride with Autothrottles chasing to keep up. It was easier just to click it all off.
Do be so quick to call it nonsense.
