Why would that make a difference?

What they seem to be doing is minimizing the tilting of their heads, just as
motorcycle racers, ballet dancers, and ice skaters do.

Nope, during any sort of flight, turns, straight and level,
whatever, a motorcycle racer, ballet dancer, or an ice skater
would still sit with a straight back and neck if they want to
continue a respectable level of flight. Hell, I do software
and IT and I sit the same as they would during flight.
