The only thing I would question about that approach is that AUTO purportedly turns the headlights off altogether if ambient light is sufficient. One would probably want to test that feature to see how well it works at dawn, dusk or in the rain.
I say "purportedly" because I have not tested it. It it happens to be as inconsistent as some features (rain sensing wipers and lane keeping) it might not do its on-off thing to one's satisfaction.
Of course you could just skip the overthinking and move the stalk to the bottom old standard "on" position in dim ambient light. My, oh, my, how did we ever live before automatic headlights.
