in picture #1 he is inverted, and hanging in the straps, that's a LOT of forward stick deflection, and he may just be giving her a little "poooosh", to stop the nose from coming on through and extending the horizontal line... do we have video of this particular inverted segment...
He's inverted and pushing at least -1G. This cat may be the new J-20 solo demo pilot, he's not afraid to "poosh it"!
