I think you hit on the context here. I can side step a bullet if I move at just the right time and the bad guy is actually pulling the trigger. The reality of doing that on purpose seems impossible and to me a bit silly.
Moving with the sidestep absolutely has value for other reasons. For me as a civilian it's more about gaining or keeping distance while I use force. And of course a side step is step one in movement. Heck it might be step one in running away. Errr.... I mean tactically retreating.
