iptables -F & iptables -X good enough *for all* tables/chains?

[Christian Seberino <seberino@spawar.navy.mil>]

iptables -F
iptables -X

These simple 2 lines seem good enough to
nuke *all* rules and *all* user defined chains.....

Yet, in print (like Linux Firewalls book) I often
see people wanting to apply -F and -X to 
*every single table one by one*

(e.g. iptables -t nat    -F
      iptables -t filter -F
      iptables -t mangle -F
 etc.)

Am I missing something? My simple 2 lines above
seem good enough to do the trick.
