The range for that test is that 1.0 is positive, so a .097, if that was your result, isn't close, so maybe they were just noting that you weren't close? I don't know why they noted it otherwise.
Syphilis isn't that common in most developed countries, and you're also less likely to get syphilis from oral sex than vaginal or anal sex, so unless you get symptoms, I wouldn't worry too much about this. If you decide to test again, test at 6 weeks, and that will be conclusive.
