Mrs Buhari can't be head of Africa's First Ladies if she's not the First Lady of Nigeria, can she?

Presidential media aide Shehu Garba said something recently that I want us to discuss. Find it below..

“Out of respect to Mrs. Buhari, the Sierra-Leonian First Lady, Mrs. Sia Koroma recently surrendered her position of head of Africa’s First Ladies to Mrs. Buhari, inviting her to take up the same seat which Mrs. Jonathan hurriedly handed over a few weeks to the handover of her husband’s government to President Buhari. Again, all these things are currently under consideration and no decision has been arrived at presently"

If Pres. Buhari has or wants to abolish the office of The First Lady during his administration, (the media has been asked to refer to Aisha Buhari as the wife of the president and not First Lady) does it not disqualify her to head Africa's First Lady, since she's technically not a First Lady? Thoughts?

I ask because Mr Garba said that they are considering it. Below are other things he said... 

“President Buhari promised that there would be a clear difference between the role played by his wife during his tenure and that played by many previous First Ladies.

“All that ostentation, ubiquitousness and arrogance we have come to expect from the office are over and done with. Change has come.

“The ideal platform from which she will be useful to Nigeria’s women and children is still being thought out. Once this has been concluded on, Mrs. Buhari’s role will become clearer to all Nigerians. There will be nothing shady or hidden about it. There will be no access to public funds. It will be purely private and voluntary."
