Confusion always comes up with a self address types. You typically have a "real assigned" ipv4-address per-interface
A floater is another type of address that's "floats ( hence the word floater ) between the active F5 in a cluster
The reasons for the floater is required for "inline" function where the clients or servers are routed using the floater as a next-hop.
The other advantage for the floater is for the determine which unit is actually active ( you can ssh and/or HTTPS ) and see the hostname of the of the active unit
It's can also not be used for any configsync operations
And finally the floater address does offer any http health checks or even in-use for client-side SNAT.
