It's not saying the law can't be repealed by majority vote. It's saying the legislature can't change the law without a seven-eights vote. The law can be repealed by voters via another ballot initiative with a simple majority.

By default, laws enacted via ballot initiatives in California can't be amended by the legislature without voter approval. California has some of the strongest protections for citizen initiatives in the country, which comes with plusses and minuses depending on your perspective.
