General Forwarding not allowed

[Rick Sample]

I searched the archives concerning this functionality but I am still a bit confused.
What this option implies and what it actually doing seem ambiguous at best. 
 
I have a form that has transaction security applied. It is restricted to authorization group 
with only managers. Only users that wear the hat (Managers) can execute that trans. Work as expected.
 
Next, I am attempting to restrict the WF Tasks to just managers of the authorization role stated above 
and NOT to allow forwarding of these Tasks to anyone. Role 168 guarantees the first part of the problem. 
'Manager of' only routes to the manager of the user approving a task. Not a problem. Works as expected.
 
Now, with 'General Forwarding not allowed' option on the task is selected, the user can still forward 
to all users in the Manager role as described above. 
 
What I want is to not allow forwarding of the Task to any user. The only thing I can think of at the moment 
is to write some method to get all Managers and exclude everyone except the user it is to route to. And of 
course, I still want the WF Admin to be able to manage the Tasks.
 
Any suggestions?
 
Thanks
