No, this happens also online Aviar.
I witness this specially against US planes.
You're both diving, the plane in front pulls a tight turn, you try to follow, drop throttle and follow a less tighter turn, but still blackout. By the time you're out of it the enemy is in your six and you have lost so much energy you're dead.
But when roles reverse this can be used against them, jerking the stick a little will make them try to follow without reducing speed, and if they're on a spit or p-51 they'll loose a wing.
