Sorry, Bat, not enough here to call someone out IMO. It looks like he is already angle up, starts to stall and wobble. Probably goes nose up for a brief second just as the warp occurs, manages to get nose down as you fly by. With nose up he would decelerate rapidly, and if the warp happened just then, you would see him continue forward breifly before the lag "caught up".
I also get most of my lag / super ball bouncing on the windscreen right as D200 goes to D0 -- I think because of the additional detail his FE tries to send to yours regarding skins, squad markings, etc. It appears this is when it happened to you/him to.
Besides, I have seen stranger things -- P38s going into intentional nose-up stalls to shoot above and behind them, wingless Spits getting kills . . . strange things happen all the time.
(BTW, I am perfectly willing to be completely wrong on this, just going by the evidence presented.)
