Can b read differently actually.
She might wanna attract only 1on1/2on1 anal bookings, no DPs etc.
She might also wanna say she'd go further if the price is right. In this case next step would be DP or DVP, depending on the offer.
A studio still might just go straight to offering her a DAPbreakin' price and she still might accept that, too. It basically depends all on her. But there is a limited number of studios interested in more really, thus her standard fare in Bp would be b/g non-anal vanilla or b/g anal.
I have the feeling she'd go much further, but it all depends on a lot of factors of course.
