I wonder if these guys reset the nose wheel steering during the cruise for some reason.
From my Airbus days, I remember if the nose wheel steering is switched off on ground due to loss of braking, nose wheel is free castering.
The problem is when the switch is turned back on, as the system does not know where the position of nose wheel in its free caster, so it will apply a full steering force left, and catch the nose wheel at the 72 degree stop, and bring it back to zero straight line again. Hence in the FCOM BSCU reset, nose wheel steering switch must always be reset on ground with park brake set, to avoid leaving the taxi way unintentionally. If the NWS reset is done for residual brakes, a mandatory log entry must be made. If the reset is made on ground for nose wheel steering, a return to the gate must be made. FCOM3, old days version.
I have not heard of a reset in flight as opposed to selecting NWS off only. I can only think a reset was made in the cruise.
