If this is allowed, why not just let #18 come in for the Libero? anyone have a case book or rules reference for this.

If you mean that 18 then subbed for 8, it's because 18 cannot come on the the libero if the libero had replaced 8. Whomever the libero replaces HAS to be the one to then replace the libero. Anyone else doing it circumvents the substitution rules, and is illegal.
