Difference between ICMP and GATEWAY_ICMP

Hi All,     This is a pretty dumb question, but what's the difference between using the ICMP and GATEWAY_ICMP health monitors.     I've read up on it but still not 100% sure what...

Gateway ICMP has a special purpose.

A Gateway ICMP type of monitor has a special purpose. You use this monitor for a pool that implements gateway failsafe for high availability.

A Gateway ICMP monitor functions the same way as an ICMP monitor, except that you can apply a Gateway ICMP monitor to a pool member. (Remember that you can apply an ICMP monitor to a node only and not a pool member.)

I still fail to understand the difference. Why isn't it possible to use the regular icmp monitor on a pool?
