Nope, not confused.
Listen to Pres Oaks opening remarks. He calls this a "unique women's session of General Conference." He then says the church is embarking on a new direction with the Saturday evening sessions, which may have varying focuses. This one just happens to focus on women. While sisters may have conducted past sessions, those were sessions for women, conducted by women. Today's session was for everyone, it was a "general session" of conference (though in person attendance was limited to the women), with a focus on the sisters. Women have never before conducted a General Session of Conference...until today.
