I was wrong yesterday. PM_SetSlotRotationAngles sets the rotation of payload in the slot. This is not affect jettison direction (but may be useful to emulate spin - banking rotation - of Shuttle payload before detachment...).
To rotate the payload slot itself (and to set jettison direction) you can use the PM_SetSlotAttachmentParams function.
I will add the notice about that in sdk documentation.
