Why don't you use:
picker=myTest in your ax.plot, where def myTest(artist,mousevnt): ... return (hit,kwdict) performs any test you like? Again, this is called separately for every Artist belonging to the Usual Suspects, but you may control whether this is the first line found, then your program just computes the distance, or the second one, then it computes the distance, and discriminates between the two. The properties kwdict passed to your callback will permit to do the rest. Or, perhaps, the first time the test doesn't do anything, and returns False, and the second time computes both distances, and finds the minimum. You have your "private" access to both lines anyway. The generalization to many lines should be straightforward.
