Howling:Into the Dalek - pathweb

This episode seems to inconsistently deal with Daleks. In Asylum of the Daleks we're introduced to the idea of a Dalek pathweb where they share information that is strong enough to delete information from every Dalek in the universe about the existence of the Doctor. In this episode if one Dalek decides it must kill every other Dalek, then why wouldn't that be shared among every other Dalek causing all Daleks everywhere to kill one another?
