When you setup TM backups on each of the MBs as long as you did not exclude any 
items from being backed up, they will be complete system backups.

System Preferences > Time Machine > click on 'Options' - Exclude these items 
from backups:
If there is nothing there on each of the MacBooks or only perhaps something not 
important to the system. It is a complete backup that TM is doing.
