Drawing regeneration - multiple models in a drawing

I have a drawing where I show two models, the original assembly and a "mirror" assembly. When yellow dot appears, the drawing is regenerated but the yellow dot persists. If the drawing model in then set to the 2nd model, and the drawing is regenerated, then it will switch to the green dot. Then the drawing is set back to the original model.

Is this normal procedure? Why does it not regenerate both models in the drawing? Is there a config setting that I could change so that is will regenerate both (or several).

Thanks, Dale
