I believe the confusion comes from Pioneer stating that you can't produce sound simultaneously from the front height and the surround back speakers at the same time. The same goes for the front wide and surround back.
Hence only 7 channels can be driven at any one time with the front heights and surround back being like a timeshare for that channel pair.
If you look at the 1522, it has the same situation. It's a 9.2 system with speaker terminals on the back. It also says that you can't get sound simultaneously from the front heights and front wides.
You can have them both setup and connected, but if one channel is being used, the other is silent for that duration.
