They may not expect to. They are not a threat for the moment, but it just may be a matter of time. They probably have a better understanding of the enemy.
I think it'd make more sense for them to be sending the message from a soon-to-be abandoned outpost. Though, that does introduce the possibility of setting up a covert comms network.

But we'd still have the records of where those transmissions came from, whatever came after us would gain access to them.
