This spaceflightnow article says near the end that the Falcon 9 2nd stage will leave SES-9 in an elliptical, inclined transfer orbit. This article says that this is a super-synchronous orbit, and that the original plan was for a sub-synchronous orbit with apogee of only 26,000km which would have then left SES-9 with a 93 day "climb" to geostationary.
I'm a little overwhenlmed by acronyms so I've left them out. but first of all what exactly do these represent: "GTO", "GSO", and "GEO".
But the main part of my question is how will SES-9 reach its target geostationary orbit from the inclined elliptical orbit described in the first article? I found this in GitHub which points to the image below, but that's clearly for a different initial condition.
