Bashshar Ja`fari and the three PhDs

In his interview Al-Akhbar, it was said that Bashshar Al-Ja`fari has 3 PhDs.  So I asked his interviewer and she told me that it was stated on his resume: "Dr. Ja'afari received two Doctorates in Political Science, one from the University of Sceaux in Paris , France and another from the University of Paris La Sorbonne in 1989. Dr. Ja'afari received a third Doctorate in 2002 in the History of Islamic Civilization in South East Asia from the University of Sharif Hedayatuallah in Jakarta , Indonesia." Now here is what I want to know: why and how did he pursue two PhDs in the same field simultaneously?  And then got a 3rd from Indonesia.  Did he go there and study or was that an honorary one? Inquiring minds want to know.
