BBC News editorial guideline change in references to Muhammad?

In Free speech protest to be staged, one can read the following:

The protest has been organised in response to the uproar over cartoons of the Islamic prophet Muhammad, which appeared in some European newspapers.

The Islamic prophet Muhammad is referred to as just that, “the Islamic prophet Muhammad” — a welcome change from “the Prophet Muhammad” or “the Prophet”, the first letter of the term invariably capitalised.

Could it be that the BBC News editors have modified the guideline, having understood that a little more than 97% of the United Kingdom’s population’s prophet isn’t Muhammad? Or is it simply a case of an article mentioning Muhammad written by a non-Muslim? I hope it is the former.
