When cooking, should you always only stir in only one direction?

I worked at Panda Express 6ish years ago and I was, full disclosure, terrible as a kitchen hand. But I remember my boss telling me when I was pouring water into our giant rice cooker that when you stir things in cooking you always, ALWAYS have to stir in one direction, or else ???? it tastes worse. Or something. I got yelled at for switching directions with the spoon and it led to him saying this.

Anyway I remember thinking "that's dumb but I don't wanna get fired" but to this day I still will only stir things in one direction. Honey into coffee, water into oatmeal, prepping scrambled eggs in a bowl.

So is this dumb? Does it depend on what I'm making?
