You can extrude with the profile curve at an angle if you want the entire extrusion to be skewed. Look at the current image, the edges are perpendicular to the path and so the cross section is uniform. If you set the extrude options to extrude the profile curve and maintain that angle all the edges would be angled and result would not be uniform especially around the top.
Also please clarify, you want a miter on the left side and for it to be 90 degree on the right side as your screen shot shows?
Also if you are achieving the miter by simply moving and rotating the bottom edge then you are losing thickness.
Put another way Maya has no way to extrude the profile at an angle to some arbitrary point then become normal to the path. It either has to be angled to the path for the ENTIRE path or normal to the path for the ENTIRE path.
