Comment on Gone with the wind by elsevilla

Before I ask my question I would like to say I adore you work, style, composition, and technique. But for the first time I am royally confused with this itty bitty detail in this particular art work. I colored the details that are in question so that you can follow me easier, haha (my description skills can out there).---->[link] Does the arm in blue belong to the girl that I gave red hair to, and if so, why does she have three arms?

I hope this makes sense and this isn't too bizarre of a question, but for some reason I really would like to know, haha.
