Meteor users - Multiple User collections

I have 2 collections userlist and userprofile they are both linked to Meteor.users collection

when I filter userlist and try to filter userprofile via a publish parameter I get the single item on the server but get the userlist items instead of the limits cursor.

I thought the whole point of creating a separate collection was to get a unique listing. would the minimongo not create a unique collection for each instance.

Its not great as I have to filter it on the client side but the list is at least limited to that users group, so ill work with it.
