I concur with you. Speculations about J-A reunion are merely that and not to be taken to heart. Such action conveys the wrong teachings. Besides, they would be condoning bal vivah. With a reunion, the show would be advocating the very opposite of what they want.
Honestly, I was initially momentarily concerned about Anandi's FBs. But on hindsight, after looking at at it from her POV, and giving her to benefit of doubt, she is probably insecure and fear has gripped her. The colossal failure of her first marriage despite being together for 16 years failed. Each ritual is going to resurrect the old memories that she has to-date buried deep within her soul.
Her current state of FB, and the fact that Jogia is returning should not be taken as indication that she is going to forgive and reunite with Jogia.
