Can WTS VLAN be the same VLAN used by Witness Host for Witness trafic?

Hello guys,

In case of 2 node deployments, I read that there would be another VMkernel on the hosts dedicated for Witness trafic (WTS). My question is, can I configure this VMkernel on the same subnet as the vmkernel on a virtual vSAN Witness Host that is used for vSAN trafic ?

If yes, in what cases the WTS VLAN should be different than every other VLAN in the infrastructure?
