It can't be!
... can it?
How would you install it, if it was a welded joint? The whole thing would be almost unmanageable to get into the vehicle; and then imagine the size of the box the part would need to be in for shipping...
I'd also like to see what the tab (arrowed in the photo below) does. It seems it would need some form of positive attachment at this point to stop the divider sliding/flapping left/right when viewed from the rear?

Actually, scratch that. I see there are two tabs, one welded to the half height barrier and one welded to the divider; and then joined together with a bolted fastener.
It can't be coincidence, can it, that this one and the one in the configurator both line up with the unequal split in the rear seats?
