If they can explain how the alternator can energize one headlight circuit and not the other, I might give that some consideration. I would want to connect a volt meter to the headlight circuit and see if voltage is present on that circuit when it happens. Now that I think about it, I wonder if a loose low beam filament could be contacting the high beam filament under acceleration and causing this. Try a different bulb or switch the bulbs from side to side and see what happens.
