Possibility of HSV1 - oral and genital?

[swamper8]

I'm considering entering into a relationship with a woman who has HSV1 - genital.  She got this from an ex who had HSV1 - oral and performed oral sex on her. (unknowingly)   Her doctor has told her, and she has told me, that she CANNOT have HSV1 - oral because she already has HSV1 - genital.  I am unable to find conclusive info on whether it's possible to have HSV1 in both places.

  I'm having a hard time figuring out how she got HSV1 - genital from him (during oral sex) but never got HSV1 - oral, from making out etc.  There must have been a very very narrow window where he was shedding/had a sore and performed oral sex on her, so the virus entered as genital and now oral is off the table?

    I'm not so much concerned with the HSV1 - genital right now, I am just nervous about even kissing her.  To add another layer of complexity to the problem, for the first four years she had it, she tested positive. For the last two years, her herpes tests have come back negative.  She does take a pill to suppress it. (every day)  I consistently test negative on 10 panel STD tests. (including HSV1 & 2)  While I'm ok with eventually getting it (EG if we got married) I don't want to pick it up just from someone I'm dating.
Thanks!
