dynamic parameters for actions executed by executeMultiple

[geekyme]

In the docs, I see this:

loadStuffForUser: [
            'loadUser',
            {
                // will be executed after 'loadUser' task completes successfully 
                action: require('../../actions/loadStuffForUser'),
                params: context.getStore(UserStore).getGUID()
            }
        ]

getGUID is ran at runtime when executeMultiple is called, so wouldn't the user not be loaded by the time the action "loadStuffForUser" is called?
