As I understand it, Dr O'Leary is a philosopher who specialises in medical ethics, and has taken a particular interest in how medical ethics applies in poorly understood and frequently misdiagnosed conditions that are swept up in the MUS/BDD etc classifications. So her focus is on writing papers about the ethics of such mis-classification from a philosopher/ethicist perspective.
Perhaps her misunderstandings about the complexities of WHO classifications demonstrates a lack of expertise in areas beyond her training, or a lack of attention to the detail of the sort that @Dx Revision Watch has developed through focusing on this area. In which case, it is concerning that Dr O'Leary is offering herself as the expert to advise Forward ME on this.
