The 

host
parameter is not the F5 device. Rather that is the 
server
parameter.

The 

host
parameter is an alias for the 
address
parameter which is the IP address of the pool member you are acting upon.

The 

ansible_default_ipv4
variable is usually the self IP address of the external vlan of the LTM.

The use of the 

ansible_default_ipv4
parameter in the examples is a bit confusing. It would have been better to just make up some IP addresses to represent the downstream servers in the pool.
