A quantum system interacting with a repeatedly measured one undergoes a non-unitary time evolution pushing it into some specific subspaces. We deeply investigate the origin of the relevant selection rule bringing to the light its connection with the "survival probability" related with the two-system interaction. The possibility of inducing an effective dynamics in the distilled subspace just during the distillation process is demonstrated.
