Having Eos out prevents you from using any of Selene's abilities, vice versa. Apply that towards having Seraph. As for the other abilities, it is more an indirect form of exclusivity. For instance, Aetherpact is forcing your pet to heal bomb a specific target, pretty much like a macro'ed Embrace+Adloquium of the olden times. Dissipation is just a way to give you a self buff to give more potent shielding and more stacks when the pet will not cover.
