Channel targets undead or living, not both?

A good cleric (or one who worships a good deity) channels positive energy and can choose to deal damage to undead creatures or to heal living creatures

(and the same wording for negative energy)

Am I reading that correctly in that if I stand in a crowd of undead and living, I can either heal the living or harm the undead by channeling positive energy, but not both at once?
