I never did them perfectly simultaneously, but I'm sure it's a similar effect.
Are you sure this is it?
I mean if you would do this but not completely syncronized (for example one window is still just half way and going and the other one near the top, this would also happen. I mean the bus voltage would just as equally drop.
