Nested subRoutes data is called in reverse order than activate

[sztrzask]

Consider the following:

   router.map(
                {
                    '/authorization': {
                        component: App.Authorization,
                        subRoutes:
                        {
                            '/': {
                                component: App.List,
                                name: 'list'
                            },
                            '/list': {
                                component: App.List,
                                name: 'list'
                            },
                            '/item/:id': {
                                component: App.ListItemDetails,
                                name: 'item-details'
                            }
});

refreshing the page at /authorization/list route calls transitions hooks in the following order:

authorization  activate
list  activate
list  data
authorization  data

Shouldn't data be called in the reversed order, i.e. the same as activate hook? If this is by design, then could the docs be updates? So far nothing suggest that data is called in the reverse order to the authorization.
