[LOTR] What is up with the Witch King and Gandalf?

In the extended edition of Return of the King, why and by what means does the Witch King break Gandalf's staff? Where does that come from? What does it imply?

The Witch King, as a wearer of one of the nine rings of power, has some of Sauron's own power, his malice and will to dominate, flowing through him. He is empowered by it and by Sauron.

As such, the Witch King was able to use sorcerous means to break Gandalf's staff.

Gandalf, remember, had most of his power locked up by his mortal form. He was charged not to directly fight Sauron and his evil, but only advise. This was why he could fight the Balrog at full strength. It was not a servant of Sauron.

The Witch King, obviously, is not under such restraints, and does not have his full power limited.

It implies that the Witch King may be equal, or greater, in power to Gandalf. While breaking the staff does not limit Gandalf's power, it is a symbolic gesture on behalf of the Witch King that he can break Gandalf as easily as he broke his staff.
