"Modern" bike frames now usually have a sloping top tube and longer seat post than was common a generation or two ago. That gives some of the advantages you suggest.
But no, the reason for a lady's frame is so the lady can mount the bike while wearing proper lady garments without making an exhibition of her lady parts. It's all about wearing a skirt. There is no performance advantage, and lady's frames are poorly suited to competition.
