Heh i was just thinking about that while writing that and finding link about it.
Reading the exact quote it sounded like N950 was just thrown out there because of what he said about this device being successor to N900. Media all around sure have made it a fact that this MeeGo or Harmattan device is N950.

Though like said the name isn't the important part, even it's internal name like RM-XXX could be more revealing than the name made up by the marketing department month before announcement.
