Yeah but I'm asking how does that help? As the phone hops around, the IP address will change, whether it's v6 or v4. Are they expecting IPv6 will be stable no matter where in the world you travel?

Yeah I agree on that, they already mentioned that part.
I think the bigger issue is the number of mobile devices behind CGNAT.
