Sometimes you may want to leave the cabal and have an assassin waiting outside or you want to gate into a situation where you might get subjected to insta-kill attacks(such as vs necromancer). The latter situation allows you to rest up your mana for an hour or two before gating, so you can get into the situation all recharged.
