Paulo spotted the issue. What determines whether a given point in the
search list "is not matched to a closer point"? Your 1-to-1 match
will be sensitive to the input ordering of the target list. The
intention of match_radius is to specify the maximum separation beneath
which all matches are "equally good". For example, the statistical
uncertainty in the position itself. Multiple matches would then imply
either is an equally good match. If you still wanted to do this (for
example if you are conducting a match for which sub-match_distance
separations are still meaningful), it will have to be a pre- or post-
processing step, since all matches are performed in parallel (which is
what gives MATCH_2D its speed).
