Match command matches wrong end of the curve. Flipping direction of one curve with Dir command does not help. The attached Rhino model file contains two planar curves which are good example of this bug.
I have tested it many times and I am sure that it does not work on my computer, no matter what I do. The following screenshot illustrates Rhino behavior when I pick wrong end of one of the curves - the match curve has strange kink in its middle.
