You can join both.
Or you join only one and you do your best to fly only on airlines that belong in the corresponding alliance.
Thiss said, it may not make much sense to join an airline that don't really plan to fly on.
Now it may be that the BR or CI programs are not very good. So, do your homework and compare.
