The document that exist is the solution guide which describes clone pools, not awfully descriptive but maybe it is of some help:
sol13392
But also of note is the built in help text for clone pools:
Clone Pool (Client)
Replicates client-side traffic (that is, prior to address translation) to a member of the specified pool. Options are: None, and entries for each already defined pool. The default is None.
Clone Pool (Server)
Replicates server-side traffic (that is, prior to address translation) to a member of the specified pool. Options are: None, and entries for each already defined pool. The default is None.
