Why am I having trouble with Sweep?

I have drawn this:


And Sweep works as expected. The path is on the Top plane of Sketch 1. The triangle is on the Right plane of Sketch 2, and its top apex is Pierced to the path on the top layer.

However, when I attempt to add the path behind the Right plane, I get this:

What am I doing wrong?

Simple Problem: A sweep only works in one direction. In this case starting at the leftmost point in your picture. The sweep doesn't care if the path is on the profile.

Do two separate sweeps for each direction or sketch the profile at one end (point-line-plane)

Yes, as florian says the sweep only goes in one direction.  When the profile doesn't start on the end of the path, sweep still tries to apply the path as best it can in that order, often giving unpredictable results like that.
