Actually that is also caused by the auto-place mechanism getting used. The auto-place can be kind of arbitrary about which direction it decides is the "up" direction when it automatically moves things into place, I think right now it may not quite work as expected if your profiles are drawn in a different view than the Top view.

If you move your shapes up to get auto-place turned off, you should also see that strange rotation disappear at same time as well.

There definitely does need to be some work to make auto-place have a more expected "up" direction when it kicks in, but probably your best bet for now would be to move those profiles up so that mode is not kicking in at all for this thing.

There is a twist parameter, but it is for controlling the behavior for how paths that move around fully in 3d up and down like a roller-coaster will behave, it won't actually control anything for your flat path like in this case.
