I assume they're doing the same thing I am. The cell network
interface is just a p2p interface, and the whole /64 is routed to the
phone/tablet. You can configure the p2p interface address as a /128
and configure the /64 on the wifi interface. My understanding of the
3gpp specs is that the cell provider won't have an address in that
/64, so you won't conflict with anything upstream of the phone/tablet.
Here's a screenshot of my (wifi-only) tablet getting v6 while tethered
through my phone:
