Naw, I raised this issue in a previous thread! Pres must be scanning FR. (Yeah, right.) They altered the marriage documents, so they are not legally binding as they are not the officially sanctioned State documents. What's more, it's not likely City of SF would use different documents for heterosexual couples because they wouldn't want to "discriminate" against gays by using a separate set of documents. So if you were clueless about what was going on with the gay marriages and you had a heterosexual marriage in SF after obtaining a marriage license during the last week, you may find out later on that you were never legally married. Lawsuits a plenty may happen down the road!
