Hi phelps and welcome to our forum. Paulina from our team told me that it's not log off but rather lock and privacy/blank mode is used.
Currently for security reasons we have done automatic lock when you disconnect from a remote PC which has the screen blanked (and keyboard /mouse blocked). If it was not done then after disconnect the remote PC would be left visible and not locked (allowing access to the desktop for someone that would have physical access to your remote PC).
We can add such an option but still it's not secure to do so.
Can you explain your use case?
