On "our" AH's the aircraft symbol (usually a wing-symbol on modern EADIs and PFDs) is stationary and the horizon behind it moves. So during a left turn the horizon will turn right...
The Russians have it the other way around; the horizon is stationary and its the aircraft symbol that is moved. As if you were viewing the aircraft from behind.
I don't know why, but I find the Western approach much more intuitive even though people new to flying find it confusing at first. But whenever I see a picture of an AH in a non-level attitude I always know instantly which way I would move a yoke to level the aircraft - as if it were a reflex.
