Question about Xilence Performance X

According to digitec's specification, the network part has 2 x 6+2-pin PCI Express. According to the picture, these (red) are modular.
If you look at the Xsilence page, 4 x PCI-E 6+2-pin (GPU) are specified there. According to the instructions, however, these are Y-cables. You can also see this in Youtoube reviews (which are quite helpful with these questions).
In reviews about it, you can read that they are Y-cables:
"2 PCIe cables with 2 x 6+2pin connectors each".
