This is good advice. Your inner ear can (does) suffer from 'coriolis effect' if you move your head in one plane, while your aeroplane is moving in another. This effect will cause dizzynes and motion sickness - reduce head movement during the manouvre to minimise/eliminate the effect. There is really good reading in the various Human Factors study books (especially at ATPL level.).
I have heard that before it was understood, this was the cause of many fast jet crashes when at low level, due to the positioning of various controls (the undercarriage selector in the early F104 was mentioned), and the repositioning of items that needed a visual check, while under high g loadings eliminated this diszzyness/disorientaion.
