I'm pretty certain he was referring to the mechanical oscillations. The sun glare on the lens coupled with the mechanical oscillations (four sets of props, rotating motors) and the gimble slightly lagging the oscillations it's trying to compensate for. Bearing in mind that I may not of entirely understood the explanation.

Basically he told me, "Try it, you'll see." and I trust he has the real world experience to addressing various hardware and software glitches that are bound to crop up in complex systems.
