Lifesaving Side Stroke

Question
I was always taught to bring the leg closest to the surface back and lower leg forward. Where can I find pictures or diagrams showing top leg back as every place I have looked show top leg forward.  Is there a variation on which leg goes back ?

Answer
Mary-- The top leg back is used for lifesaving for two reasons:
1.  So the rescuer still has a strong kick while swimming and
2.  So the victim doesn't get kicked during the rescue.
Traditionally, the top leg is supposed to go forward.  I really don't know of any diagrams available.
hope this helps,
