no, given that /usr/sbin/iptables is clearly a administrative command and so there is no valid reason to seek for iptables in /usr/bin/ nor have it as override is a logical conclusion if you want to override things /usr/local/bin and /usr/local/sbin are your friends - however - back to topic: "Incorrect order of /usr/bin and /usr/sbin in path" is plain wrong and the PATH /usr/sbin:/usr/bin is in any case correct - period
