CSOM Javascript - when executing query on multiple lists getting error - SharePoint 2010

Is here any SharePoint expert, who can help me find out, why I am getting error on lists queries?

I am trying to fetch data from multiple list asynchronously, but I am getting following error: The collection has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested.

My code looks like this:

function loadAllData() {
    loadTeam();
    loadTasks();    

    loadTaskTypes();
}   

Where load functions looks like:

function loadTeam() {
    retrieveListItemsInclude(teamListProperties);
}
function loadTasks() {
    retrieveListItemsInclude(tasksListProperties);
}
...

And retrieveListItemsInclude function looks like:

function retrieveListItemsInclude(listProperties) {
    var clientContext = new SP.ClientContext.get_current();
    var oList = clientContext.get_web().get_lists().getByTitle(listProperties.listName);

    var camlQuery = new SP.CamlQuery();
    camlQuery.set_viewXml('<View><RowLimit>1000</RowLimit></View>');

    this.collListItem = oList.getItems(camlQuery);

    var includeListProperties = buildInclude(listProperties);
    clientContext.load(collListItem, 'Include(Title,ID)');

    switch(listProperties.listName) {
        case 'Task list':
            clientContext.executeQueryAsync(function(){ onTaskQuerySucceeded(listProperties); }, failCallback);
            break;
        case 'Task types list':
            clientContext.executeQueryAsync(function(){ onTaskTypesQuerySucceeded(listProperties); }, failCallback);
            break;
        ...
        case 'Team list':
            clientContext.executeQueryAsync(function(){ onTeamQuerySucceeded(listProperties); }, failCallback);
            break;
    }
}

And finally success callbacks look like:

function onTasksQuerySucceeded(listProperties) {

    var tasks = [];

    var listItemEnumerator = collListItem.getEnumerator();
    while (listItemEnumerator.moveNext()) {
        var oListItem = listItemEnumerator.get_current();

        var task = {};

        task.id = oListItem.get_item('ID');
        task.title = oListItem.get_item('Title');

        tasks.push(task);
    }

    console.log("Tasks loaded.");
}

When running loadAllData() function, I get above error, when calling collListItem.getEnumerator() in all of success callbacks, but the last.

This means, if I call loadTeam(); loadTasks(); loadTaskTypes(); in loadAllData(), I get error in first two success callbacks, but loadTaskTypes() will execute properly.

Why is this happening? In retrieveListItemsInclude(listProperties), I create local clientContext for every request to SharePoint list... why are the calls interfering?

When I used jQuery promises to chain calls loadTeam(); loadTasks(); loadTaskTypes(); one after another, all data loaded without error.

I appreciate any help.
