Not an issue either except to person #2.

but what if person 1's contagious hsv was still in her mouth?
first of all person 1 would need to actually not only have to have oral herpes but would also have to be actively shedding the virus at that time. Even if person #2 contracted hsv from person #1 from that kiss - they aren't going to be contagious that quickly to transmit the virus to person #3 10 minutes later.

Well, if person one did indeed pass on the virus, I would say it is possible for person 2 to give it to person 3. I take it you are person 3?
