Impact of un-assignment of Enterprise Admin Role at NSX Manager from vCenter Admin

Scenario: What is impact of un-assignment of  Enterprise Admin Role at NSX Manager from vCenter Admin which is used for vCenter Registration in NSX Manager?
 
Whenever vCenter Server is required to be registered in NSX Manager at that time vCenter Admin Role User is needed for this  registration process and NSX Enterprise Admin Role automatically gets assigned to this user. As you can see in this below given screenshot

Answer:
I have manually unassigned the Enterprise Role from the vCenter Admin User Account, as you can see in this below given screenshot

Immediately error message gets pop up "Could not establish the communication with NSX Manager. Please contact administrator"

And NSX manager become unknown in vSphere Web Client

To Fix this "I have re-connected my vCenter Server in NSX Manager Admin Console" by just entering the credentials again.
Bingo "It's back in NSX Manager" and Role gets assigned automatically again

Note: If this enterprise admin role is manually un-assigned from any other account to whom it was manually assigned then this will have no impact on NSX Manager.
