Align to Face aligns the curves with Mesh faces. This ensures that, after having converted to a mesh, the curve has a proper geometry. This would facilitate better mesh conversion of the curves and can be quite a powerful option for 3d modeling using Bezier curves.
The tool is available in the latest add-on version (0.9.81 or newer).
Please note: the tool will appear in a separate category below 'Join Bezier Curves' and not as a single button as shown in the demo. I will probably be creating a separate video explaining the options some time soon.
