who knows? They may even let you in on the secret of that instant turn........ 
you mean the one where you miss ur guns pass and all a sudden he's on your tail? nothing more than a slight turn and roll out then roll back in as they overshoot. it's all about timing, especially in obtaining a shot oppt'y afterwards.
there's also a variation that involves a little more turning....defensively, as the bogey gets around 800 out (in AvA w/weaker guns) you turn back into the bogey on your tail and as you merge, you're re-turning back onto the bogey who is starting his extension from the pass. timed right you can end up fairly close on their 6 with a shot that might pressure them into turning. imagine a tight "S" inside of a "U."
both situations are all about speed management.
i was playing around with Larry, my 109 vs his otd hurri... i repeatedly buzzed him for a while, and he'd do teh roll out and back in... i'd evade and rinse wash repeat.. til finally after i got bored of toying with the hurri, i dropped down in the pursuit slot and as i closed aroudn 800 behind him, i eased up on throttle... since our speeds were more comparable (and i was anticipating that defensive rollout) all i had to do was slow down even more and as he made that move around 400... it wasn't too hard to pull into him for the shot as our speeds were similar. this occurs around 8:30 in the film.
in the film of this encounter (9 mins, lol) you'll see larry perform that rollout/back manuever multiple times, occasionally latching close enough to force me to waste a little time extending and alting again. i used the 109's speed advantage, refusing to go into stick-to-tummy turning where the hurri has the advantage, especially on the deck. i can tnb w/hurris, yeah, win some, lose some, but my point in this encounter was to get inside larry's head, lol. i was in no particular "hurri" - heh - to kill him, but you can see how easy it could be for me to make a mistake and end up with a tail full of lead. the *key* to defeating this is to either take ur time, or more riskier, as you're closing in on the bogey, cut your speed in anticipation and drop right in on their 6... and don't miss.
watch it in fixed with pan and zoomed out w/trails on so you can literally see the moves better. once you do that a few times, jump into one of the planes and see it from their perspective - more or less.
here's the film:
