Well no. I already knew PCIe could be hot plugable and also knew it
usually is not. expresscard on the other hand always is, I just forgot
it existed and didn't think the device in question would work with that.
Brain initially says: PCIe attack implies desktop which doesn't have
hotplug implies this is irrelevant. :)

If I had watched the video from the start initially it might have helped.
Unfortunately youtube helped and made the link you posted start at a
few minutes from the end. Youtube can be annoying at times.
And yes the "over usb3" comment did give the wrong initial impression.
In the end it does seem like a neat trick.
