This is a default floating rule to emulate the previous floating behavior for new installs and upgrades.

One member:

This would permit a copy to float anywhere within a system, but would return to the system if it was returned elsewhere.

One member:

This would permit a copy to float to any branch, but not to sublibraries or bookmobiles.

One member:

This would permit a copy to float to any branch in a system, but not to sublibraries or bookmobiles, and returning to the system if returned elsewhere.

One member:

This would permit a copy to float between BR1 and BR3 specifically, excluding sublibraries and bookmobiles.

It would consist of two members, identical other than the org unit:

This would allow an item to float anywhere except for BM1. It accomplishes this with two members.

The first includes all org units, just like Float Everywhere:

The second excludes BM1:

That works because excludes are applied first.

This would allow an item to float into BR2, but once there it would never leave. Why you would want to allow items to float to but not from a single library I dunno, but here it is. This takes advantage of the fact that the rules say where we can float to, but outside of stop depth don’t care where we are floating from.
