Multiple views and multiple tabs .. $ionicTabsDelegate is which?

For a tablet view I use the MultipleViewsManager.

I have 2 views which have both have tabs on them.

if I use the $ionicTabsDelegate to do something with a tab on a perticular controller on one of those views I get multiple
instances inside $ionicTabsDelegate. which instance is which tab ?

for instance if I do $ I see both tabs updated.
