The local axis pops to the origin because the newly created polygon surface is considered a new object and the local axis origin of all new objects is the global origin (0,0,0).
There used to be an option to delete the nurbs geometry a long time ago. What you do now is just delete it manually afterwards. If you want to keep the nurbs geometry around just remember is will have history on it attached to the new poly surface so be careful.
