Yes. The NS records list reddit nameservers (usually you need to use CF nameservers for using their service, using your own nameservers require more config) but the A records list CF IPs (free users just get two IPs, reddit has quite a lot)

Huh, interesting. I didn't even know they'd allow you to do that. I assumed CF requires full DNS control to allow quickly switching over IP's in case of DOS and such.
HN does it via CNAMEs (this doesn't require manual editing of the IPs and CF can do it when they need to):
