Streched cluster and Affinity Rules

Hi

in a vSAN streched cluster it's possible to use DRS soft affinity rules  to set a Preferred Fault Domain for a bounch of VMs.

If I need to move (vmotion) a VM or some VMs to the Secondary Fault Domain (without having any failure) what happens?

DRS will enforce the soft affinity rule and vmotion back the VMs to the preferred site? 

And the same question for a simple, not streched, cluster. If I have a soft rule to prefer a couple of hosts for some VM and I need to move a VM to an host 'not preferred' what does DRS do?
