Exactly. The basic idea behind this is to be able to have multiple 
services to authenticate against and have priority on them to use them 
"in chain". Then the first one that can authenticate the user "wins" and 
other services are not called.

If you want to activate different services according to different 
subsites you have, you'll have to _change_ the authentication services 
to take this extra parameter into account. I don't say it will be really 
tricky but that's not something that is possible out of the box and 
you'll probably have to manage your modification and make sure they are 
not overwritten whenever you update the underlying authentication 
service (LDAP, ...).
