on slide 66 it shows smartphones each assigned a /64.

This is not the right thing to do, unless one agrees SLAAC should work 
with a /65 as well, for a CPE for example.

One should make one's mind either one of those:
- /64 per smartphone and /65 possible in SLAAC.
- /64 in SLAAC and /63 per smartphone.
