Makes a little more sense after going through ATL for the first time in a long time...
Add to it the 27R VASI is on the right side unlike a lot of runways, the 27R lights were on low intensity, and the fact that the center line lights on Mike are those LED's which can appear white. Add to it that it was their third/fourth runway change. Add to it the fatigue issues. See where this is going.
