Correct on all counts.

If you do need to duplicate view hierarchies with bindings intact,
you're best off instantiating a nib multiple times.  Failing that, you
can use exposedBindings and infoForBinding: to get bindings
information, and -bind:toObject:withKeyPath:options: to set the
gathered information on new objects.
