Yes that was just an example. I'm not a threading expert but basically once the basic "Spindle-Sync'ed-Coordinated-Motion" is implemented in the Controller then the rest just becomes a matter of GCode programming. In Mach3 a single threading pass is performed with G32. Then you can use the threading wizards to create various multi-pass, tool advance angle, spring-passes, tapers, etc... There is an option to either use G76 or keep it all multiple G32 codes.
yantr3d is one user. I recall he even showed me a weird cone shaped spiral thread thing he made, but I can't find the photo right now.
