I don't believe they are restricting based on worship - they are making it more flexible using worship as a means for you to qualify. Their statement is as follows:
"Live, work, worship, or go to school in Orange County, San Diego County, much of Los Angeles County, the City of South San Francisco, or the City of Alameda"
This way, if your place of worship happens to be in one of these areas, you are eligible to join. You can also join if you live, work, or got to school in any of these areas.
Sorry that you could not qualify.
