I think this quote from the article will help:

And the highest end solution, the one being used on the MSI board, has a x16 to the CPU and then a configurable pair of x16s to GPUs. You can operate this controller in 4 x8 mode, 1 x16 + 2 x8 or 2 x16. It's all auto sensing and auto-configurable.
The way I read it is that the chip communicates with CPU with a single x16 lane; It subsequently communicates with the GPUs with a 4x8, 2x16, or 1x16 interface.

DAMN THIS IS COOL
