Not sure this can be done directly through MVVM binding. The holding event won't set the selected item straight away...

If you would register to the holding event and use code behind, you'll notice the 'holded' item is only known in the HoldingRoutedEventArgs - something like this:

private async void OnListViewHolding(object sender, HoldingRoutedEventArgs e)
{
   var selectedItemThroughHolding = e.OriginalSource.DataContext as ***Model;
}

So my suggestion would be to use this code behind event and reroute the selectedItem to the viewmodel there...
