"hardware support" could just mean the GPU is capable of it and not necessarily tailored for it.
Eh, it could mean a thousand things. The fact they said "just like PS4 Pro ..." just before that makes it certainly sound like it's a similar level of support.
I could be wrong, though, hence the "I think" at the beginning of my reply. I thought I had heard it did similar things, did a quick google search and ended up on that page, so I haven't thoroughly researched it.
