helical sweep with non-circular sketch profile twisting

I am trying to create a coiled wire, which follows a non-circular helix path, with a non-circular (slot) profile.


The sweep path was created using an intersection curve between an extruded body and a helix surface.


When I sweep the slot profile, with no twist, it creates a twisted body.  To get it to "not twist" I have to put in a twist value to offset the twist...  confusing

How can I properly sketch the profile for the sweep so it stays untwisted?




Here is untwisted sweep:


Here is what it should look like (added an "offset" twist of 60 degrees):



I have attached the part.
